Detailed Outline with Links to Written Narrative


A. Introduction: What Federal Legislative Histories Are and How They Are Used
    1. Compilation of related legislative docs that precede the enactment of a U.S. public law
    2. Used by federal agencies, attorneys and courts to interpret a law
        a. At the least tells you general purpose of a law or particular title in a law
        b. Usually harder to decipher legislative intent in smaller provisions in a law
    3. Controversy about relying on documents that are not enactments
        a. Many law journal articles written debating the merits of leg. histories
        b. Recent critics, textualists like Justice Scalia, have dampened use in courts
        c. See bibliography of selected law journal articles  

B. The Federal Legislative Process and Legislative History Documents 
    1. Typically a bill is introduced, numbered sequentially & referred to committee(s)
        GPO prints bill, and frequently an intro statement & sometimes the text, summary &
        correspondence in Cong. Record, especially on the Senate side)
    2. Possible committee action on bill (most see no action unless chair is sponsor/cosponsor)

Introduction: What Federal Legislative Histories Are and How They Are Used


Federal legislative histories are compilations of related documents to a specific U.S. public law that generally precede the law's enactment. These documents can include related committee reports (including the conference report), debates, earlier texts of the bill(s), floor amendments, congressional hearings, committee prints, and other documents. The history of the bill's (or bills') development is normally set out as well including related legislation in previous Congresses. These compilations and chronologies are usually compiled by in-house legislative librarians or legislative specialists in a law firm, agency, court, or publishing company. Occasionally, histories are also produced by congressional committees or by commercial publishers often with related laws. They are bound together or placed together in a file or loose-leaf binder, usually with a table of contents. In recent years recent laws are digitally assembled or paper copies of older histories copies are scanned and digitized. Legislative histories can be very extensive, especially for laws with many titles and sections and on legislative matters that may have been percolating over several congresses in various legislative measures.

Traditionally, the legislative history of a U.S. public law is looked to by federal agencies, attorneys and the courts in order to determine the congressional intent of a particular statute or one of its provisions, especially if the plain reading of the statutory text is somewhat ambiguous. Some U.S. laws state their purpose in a preamble of findings at the beginning, but most U.S. laws do not set forth their purpose in the text. At the very least, a legislative history will usually answer the general question about why Congress is making a particular law or particular title of a law. However, what Congress intended when they enacted a particular provision in a law or what they meant by a particular word or phrase in a law is usually harder to decipher.

In recent decades, many law review articles have been written that have debated the merits of relying on documents that are not themselves legislative enactments (see law journal bibliography). Many critics, like Supreme Court Justice Antonin Scalia, advocate a strict textual interpretation of public laws. This criticism has lead to a dampening of the use of federal legislative histories in some federal courts (see "The Supreme Court’s Declining Reliance on Legislative History: The Impact of Justice Scalia’s Critique" by Michael H. Koby in v. 36 Harvard Journal on Legislation, pp. 369-395 (1999). None-the-less, legislative histories are still widely used today by the U.S. legal community as a means to further decipher the legislative intent of Congress. Even Justice Scalia has concurred in opinions that have strayed from a strict textual reading of the law (for instance see United States National Bank of Oregon v. Independent Insurance Agents of America (1993) 508 U.S. 439, noted at 12 U.S.C. 92 notes). 

The Federal Legislative Process and Legislative History Documents


In comprehending federal legislative histories it is important to know the general legislative process of how a bill becomes a law and the documents that normally accompany that process. For instance, all bills must be introduced by a member of Congress and are then referred to a committee or committees with jurisdiction over the bill's subject matter. Legislation written by the members of the President's Administration also follows this process and a committee chairman or ranking minority member may be asked to introduce such legislation "upon request". The text of the bill as introduced will be printed as a separate document by the Government Printing Office (GPO), usually a few days after its introduction. The text of a bill as introduced may also be included in the published committee hearing on the bill.

Introductory statements on a bill, accompanied perhaps by the text, summary, and related correspondence, may also be inserted into the Congressional Record by the bill's sponsor or cosponsor at the time of introduction. On the Senate side, since the 1970's, inserting introductory remarks into the Record has been the norm for most bills and they are occasionally inserted on the House side in the Extension of Remarks section of the Record. In any case, the Congressional Record will always publish a daily list of bills and resolutions introduced that day with the bill number, sponsor, original cosponsors, official caption (long title), and committees to which the bill is referred.

House and Senate bills are numbered sequentially within a Congress. A bill that has not been enacted during a two-year Congress dies at the end of the Congress and has to be reintroduced, usually with a new number, in the next Congress if it is to be considered. House and Senate resolutions are also numbered sequentially and go through a similar legislative process, but only joint resolutions (not simple or concurrent resolutions) can become law. For more details on Congressional bills, resolutions and other matters see LLSDC's Questions and Answers in Legislative and Regulatory Research.

A committee or a subcommittee may hold hearings on a bill (or related bills) or its subject matter, but most bills just languish in committee unless the bill (with some exceptions) is sponsored or cosponsored by the chairman of the relevant committee or subcommittee (chairmanships are controlled by the majority party within a chamber). Congressional hearings are generally published months after they occur but prepared statements and archived webcasts can often be acquired before that time from the committee Web site. Many unofficial transcripts of selected witnesses can often be acquired from two commercial services, Federal News Service and CQ Transcripts (Note: CQ Roll Call purchased Federal News Service on December 1, 2014) or from other commercial databases that have contracts with them. Hearings are not published in the Congressional Record, but they are normally noted in the Congressional Record's Daily Digest, published as part of the Congressional Record since 1948.

Next, a committee or subcommittee may schedule a meeting to "mark up" (amend the bill by voting in committee) a bill and then refer it, as amended, to the full committee or to the full House or Senate. Subcommittee amended versions of bills that incorporate markup amendments do not get officially printed and subcommittee and committee amendments are sometimes made available on Committee websites. They are also available by subscription from CQ Roll Call (from 2005). In addition archived webcasts of committee mark-up sessions are sometimes placed on Committee websites for a period of time. However, when a committee changes hands from one political party to another much of what was previously on the committee site is no longer presented but may be on "the minority's" website.     

A draft of a bill, instead of a previously introduced bill, may also be "marked up" by a committee or subcommittee. These draft bills, frequently called "committee prints" complete with line numbers like other bills, are not officially published, but may be available from a committee Web site right before a scheduled mark up and for a period of time afterward. 

When a bill is approved by a majority of members of a full committee it is ordered reported by that committee (normally it's chairman) to the full House or Senate. However, before a bill is officially reported, a committee report to accompany the bill is usually prepared (especially on the House side) and only then is the bill reported and placed on the calendar as a possible measure to be considered by the full House or Senate. The committee report is a key component of a legislative history as it is there that an explanation and summary of a bill can be found. Sometimes it is many weeks later that a bill, which has been ordered reported, is officially reported to the House or Senate and printed in amended form with its accompanied report. The Congressional Record notes when a bill is officially reported and what the report number is of the report that accompanies the bill. These are both printed as separate documents by the Government Printing Office, and their texts do not normally appear in the Congressional Record itself. In recent decades House committee reports usually include the text of the bill as reported (in small print) at the beginning of the report. Like congressional bills, House and Senate reports are numbered sequentially within a Congress.

If a chamber's leadership decides to bring a reported bill to the floor, it can then be debated and amended. On the House side non-controversial legislation is usually considered under suspension of the rules -- with no amendments allowed. However, controversial legislation on the House side is normally accompanied by a report from the Rules Committee which governs how the bill is to be considered and what amendments will be allowed. A resolution to adopt the rule must first be passed by the House before proceeding with consideration of the bill. The text of the House resolution to consider the bill is published in the Congressional Record as well any accompanying debate and votes. The bill itself and any of the bill's amendments are then debated and voted upon with the debate transcript, the record of votes, and the text of the amendments placed in the Congressional Record.

Unlike those of the House, the rules in the Senate allow for unlimited debate on bills and their amendments unless the Senate 1) votes to table an amendment, 2) agrees to limit debate by unanimous consent (frequently done), or 3) agrees to close debate on a bill or amendment with at least 60% of duly sworn Senators voting to "invoke cloture".

Should a measure pass one chamber, a new version of the bill as passed is prepared and generally printed in the Congressional Record (usually on the day of passage, but sometimes a day or two later). The text of the bill as passed (now termed an Act) is called the engrossed version and it is available electronically. The act is then referred to the other chamber; and it is this newly received bill in the other chamber that is officially printed in paper form and it is then immediately referred to the committee with jurisdiction.

In recent decades, it is customary for the receiving chamber's committee to be working on its own bill with a similar subject matter. Frequently the committee may report its own bill and that bill is the one considered on the chamber floor. After they pass their own bill, it is then that they take up the bill referred from the other chamber, often deleting all after the enacting clause, and inserting the language of their own chamber's bill. This bill with its new amendments will then be sent back to the other chamber for consideration. The original chamber may agree to the new amendments and thus clear the bill for the President, or it may agree to the amendments with a few additional amendments of its own before sending it back.

If agreement can not be reached between the two chambers, then a conference is usually requested by one of them (sometimes immediately by the second chamber). The other chamber will then agree to a conference and conferees are appointed from both chambers. This committee on the conference will normally hammer out a compromise text accompanied by a joint explanatory statement and send it back to both chambers in a conference report. Earlier congresses frequently had a manager's statement from just the House side or no statement at all. Even recent conference reports, if time is critical, may contain no explanatory statement or only a very short one. Normally, an explanatory statement in a conference report is the first item to be reviewed in a legislative history. Conference reports, unlike standing committee reports, are always published in the Congressional Record and are given sequential House report numbers (in earlier congresses they may also be given Senate document or Senate report numbers) and published by GPO as such. If both chambers agree to the conference report (these deliberations are also recorded in the Congressional Record), the measure is cleared for the President. Most legislation that has cleared Congress does not need to go through a conference, but controversial legislation and appropriations measures typically require a conference.

The enrolled text of cleared legislation is prepared and signed by officers of the House and Senate and presented to the President, but it is not officially published. The enrolled version of a bill is available electronically and its page formatting (in PDF) will correspond exactly to the statutory page formatting it will have should the bill become law. On rare occasions, when a bill is quite large and a Presidential signature is needed right away, an enrolled text is not prepared. However, for political reasons it may take some time, even weeks, before an enrolled measure is presented to the President, but once it is presented the President then has ten days (starting at midnight on the day he receives it, but not including Sundays and holidays) in which to sign or veto the act. Many times when he signs the bill he will prepare a signing statement which is published in the Compilation of Presidential Documents. Unless the law specifies otherwise, the effective date of a law is the day the President signs it (the date of enactment). A specific provision in a law may also have its own effective date.

A few days after a law's enactment the Office of the Federal Register will assign a public law number and Statute At Large pages to a new act, and usually a few weeks later a new law will be published in pamphlet form (called a slip law) by the Government Printing Office. Since 1975 the form and pagination that this published slip law has will be exactly replicated when it is published as part of the United States Statutes At Large with U.S. Code citations in the margin of each new section of the law. The U.S. Code citations are assigned by the Office of the Law Revision Counsel in the U.S. House of Representatives, usually during the enrollment process. At the end of the text (also since 1975, but since 1963 for slip laws) will be brief legislative history notes, including bill numbers, committee report numbers, dates of floor consideration, and any Presidential signing statement citation to the Weekly Compilation of Presidential Documents.  

Finding Already Compiled Federal Legislative Histories


If there is a tangible copy of a compiled legislative history of a specific U.S. public law the easiest wayto obtain it is to borrow it from or go to a library that has already compiled it. The Union List of Legislative Histories, 7th Edition (2000) and 2002 supplement, published by Law Librarians' Society of Washington D.C., Inc. (LLSDC), contains an extensive list of thousands of legislative histories owned by member libraries. A list of many other federal legislative histories, published either by commercial firms or by a congressional committee with jurisdiction, can be found in Sources of Compiled Legislative Histories by Nancy Johnson (2000, Fred B. Rothman & Co.- now William S. Hein & Co. and digitized on its subscription Web site, HeinOnline.org). Johnson’s publication is updated biennially and includes references to many law journal articles discussing the legislative history of specific laws. Another resource is Federal Legislative Histories: An Annotated Bibliography and Index to Officially Published Sources compiled by Bernard D. Reams (1994, Greenwood Press). This work, now out of print, also has detailed descriptions of government produced legislative histories (usually committee prints). Once you find a published legislative history of the public law you are researching, you can search for that book on OCLC in order to find a library that may own it or you can purchase it from the publisher (assuming that it is still in print). You can also make requests for legislative histories on various law library listservs like LLSDC and LawLib.

However,it should be noted that for U.S. public laws since 1995 most of the materials needed to compile a legislative history can be obtained for free from the Congress.gov database of the Library of Congress, including downloaded PDF documents for bill texts, Congressional Record pages, and Congressional committee reports. In addition the GPO's FDsys database contains bill texts (from 1993), Congressional committee reports (from 1995), the Congressional Record (from 1995), and Congressional committee hearings (from 2001 and many before that time). Links to some 70 compiled histories on the free Internet are also available on LLSDC's website Legislative Histories of Selected U.S. Laws on the Internet: Free Sources.
Commercially, thousands of legislative histories are now available electronically on the databases of Proquest Congressional Insight, Westlaw, and HeinOnline as well as bill histories and related links on the databases of LexisNexis, CQ Roll Call, and Proquest Congressional,  Proquest Legislative Insight includes thousands of comprehensive legislative histories from 1789 to near present Congress but does not include amendment texts and extraneous remarks), The Westlaw Fed-LH premium file has thousands of carefully compiled GAO legislative histories from 1927 to 1994. HeinOnline has hundreds of digitized legislative histories from Congressional committee prints and those from the collection of the law firm of Covington and Burling). For more details about these services see LLSDC's Legislative Histories of Selected U.S. Laws on the Internet: Commercial Sources as well Finding or Compiling Federal Legislative Histories Electronically and Federal Legislative History 101. In addition to these resources Tax Analysts, Inc. produces a electronic product that contains the committee reports on most all the tax legislation enacted since the 99th Congress (1985). Some other publishers and organizations may produce electronic legislative histories as well.

At various times certain commercial firms have also attempted to place full-text federal legislative histories on microform. Information Handling Service (IHS), in its Legislative History Service, compiled histories for selected U.S. public laws (primarily tax laws) from the 61st to 96th Congresses (1909 to 1979). IHS has a hard copy index, "The Legislative Histories Indexed Guide", that accompanies the collection. Another company, Commerce Clearing House (CCH), in its Public Laws - Legislative Histories Microfiche, compiled histories for all U.S. public laws from the 97th to the 100th Congress (1979 to 1988 - no hearings included). Various libraries around the country hold these microform collections (now out of print) and a search on the Online Computer Library Center (OCLC) may reveal those holdings.

By far the most commonly available federal legislative history collection is the one under the misleading title United States Code Congressional and Administrative News (USCCAN). Published by the West Publishing Company (now Thomson West) since 1941, USCCAN is a regular staple in most U.S. law library collections. This annual publication does not reproduce the U.S. Code, nor does it contain congressional and administrative news articles. However, it does reproduce the text of all U.S. public laws and provides some of the important legislative history material for most of those laws. These include explanatory statements to most related conference committee reports (but not those to appropriation bills), the selected texts of related reports from standing committees (no more than one), and all Presidential signing statements (since 1986), executive orders and Presidential proclamations. The service also contains references to companion committee reports and dates of consideration on the House and Senate floors (since 1964), legislative history tables (since 1964), as well as indices to subjects covered, to U.S. Code sections affected that year, and to popular names of public laws. There are also annual lists of House and Senate members, standing committees and their members, and the names and titles of the President's cabinet. In earlier volumes (1945-1954), there were lists of U.S. government agencies and information on their origins. From 1948 forward, conference report joint explanatory statements, committee reports and Presidential signing statements (since 1986) can be foiund on on Westlaw's LH file.

It is important to note that references to USCCAN legislative histories in West's popular United States Code Annotated (USCA) do not always contain relevant information to the specific U.S. Code section being referenced, especially if the public law's history being referenced is particularly large or complicated. USCCAN is a good starting point, but it is by no means all-inclusive for pertinent legislative documents.  

Compiling a Comprehensive Federal Legislative History in Paper Format


The arrangement of documents in federal legislative histories may vary considerably, but they should generally contain the text of all of the important documents or at least cites to them. Documents in some histories are sometimes arranged in chronological order. Others are arranged in reverse chronological order and still others are arranged by document type, by each title in a public law, or some combination of the above. It is up to the discretion of the compiler how best to organize the related documents.

Large legislative histories that are bound usually will have similar sized documents bound together. In these histories the public law itself in pamphlet form, known as the "slip law", is usually placed at the beginning. The law may be followed by the similarly sized conference report (if there is one) and the related reports from standing committees. Frequently, related bills (as introduced, reported, and passed) are bound together. In a similar manner related remarks, debates, votes, amendments, bill texts, and Daily Digest pages, photocopied from the Congressional Record, are also bound together. With the Congressional Record pages might be placed a photocopy of the Presidential signing statement excerpted from the Weekly Compilation of Presidential Documents. Related committee hearings (sometimes published long after the law's enactment) are also usually bound together. Finally, other miscellaneous documents such as related committee prints (studies, side-by-side comparisons or early bill drafts), House and Senate numbered documents (usually accompanying a Presidential communication like a veto message) or Congressional Budget Office reports may be bound together. Because of the diverse and lengthy nature of many legislative histories it is important for the compiler to prepare a title page and a detailed table of contents (or chronology of actions) which can be placed at the beginning of each volume of the history. Some histories can be very short with only the law, the text of the bill, a few pages from the Congressional Record and with one or perhaps no reports. However, for some large public laws with multiple titles and perhaps a history in prior congresses, a compiled legislative history may be more than 30 bound volumes long.

To make compiling legislative histories easier, Proquest Congressional Information Service (CIS), has, since 1984, produced an annual legislative history volume that contains citations and abstracts to most of the aforementioned documents related to each U.S. public law of a non-ceremonial nature and to all public laws after 1998. In the annual volume each public law is summarized, related Congressional reports are abstracted, references are given to related bills as are references to the dates of consideration on the House and Senate floors (there are no CIS abstracts of debates). Related committee hearings and prints are abstracted, and citations may be given to other miscellaneous materials like Presidential signing statements. CIS legislative history volume accompany the annual CIS Index/Abstract volumes that cover all congressional committee hearings, reports, prints and documents. From 1970 to 1983, limited legislative history citations to each U.S. public law were placed in the back of annual CIS Index/Abstract volumes. CIS legislative histories have become a standard tool for compiling recent federal legislative histories; from 1970 forward, they can be found on the CISLH file on LexisNexis with hypertext links in recent years to the full text of bills, committee reports and Congressional Record pages with floor consideration. LexisNexis Congressional, available to academic institutions, also has CIS legislative histories with many hypertext links to related full text documents.

While the many documents cited in a CIS legislative history may seem like overkill, it is important to note that some CIS legislative histories may not be comprehensive enough. Left out are references to introductory and extraneous remarks and some bills referenced in the history may also have extensive legislative histories themselves with related committee reports and their own floor consideration, which are not noted. There are also other documents that relate to a law's legislative history that CIS legislative histories do not cite or abstract. These may include related published reports from a federal executive agency, the General Accounting Office, the Congressional Research Service of the Library of Congress, or another body. They may also include unpublished bill drafts, committee markup amendments, committee markup summaries, draft bill comparisons, and unofficial transcripts of conferee deliberations. Also outside the scope of CIS legislative histories are congressional press releases, correspondence, and news articles, any of which may have importance to a bill's legislative history and answer the question of why Congress did what it did. However, note that in a court of law, the further you stray from the actual text of the law, the less likely it will be acceptable to a judge.

Compiling a Federal Legislative History Electronically


What if you need to produce a legislative history before CIS has produced its annual legislative history volume? As you may know, frequently attorneys and other patrons want those histories soon after a bill has been cleared for the President or even for bills that will never reach the President’s desk. What's a librarian to do? Fortunately, for recent Congresses, most of the material in a federal legislative history will be available electronically on Congress.gov, GPO FDsys or commercial services. You just have to do a little research to find out which documents relate to the bill or law in question. A near comprehensive guide to electronic sources available for this task is contained in the document "Internet and Online Sources of U.S. Legislative and Regulatory Information," found on the web page of LLSDC’s Legislative Source Book. Also on the Source Book is "Electronic Sources for Federal Legislative History Documents with Years/Congresses Available."

Congress.gov, a free service of the Library of Congress, is a good starting point. It has a reasonably good bill summary and status tracking system (as far back as 1973). If you have a bill number you can easily obtain the references and links to bill texts, committee reports, Congressional Record pages of floor consideration and amendments, the companion bill in the other chamber, and even when hearings were held on your bill. Congress.gov bill action service will not tell you what someone said in testimony, nor when someone made extraneous remarks on a particular bill, or what are all the other bills and reports that may relate to the bill that was enacted. But you can do research on Congress.gov or on congressional committee web pages to obtain most of this information. One drawback in conducting research on Congress.gov is that it does not utilize Boolean terminology (and, or, near, etc.). Congress.gov has the full texts of bills from 1993 and the Congressional Record and congressional committee reports from 1995 forward. Congress.gov does not have hearings, but House and Senate committee websites will have prepared witness statements and frequently archived webcasts.  Congress.gov replaced the older THOMAS database but does not include the THOMAS non-PDF bill text files from 1989 to 1992 or the non-PDF THOMAS  Congressional Record from 1989 to 1994.

GPO FDsys is a free electronic document service of the U.S. Government Printing Office, which is the legislative branch agency that publishes most congressional and many other government documents. Included on GPO FDsys are the Congressional Record Index and History of Bills from 1983 forward, History of Bills with page and date cites and bill texts from 1993 forward, the Congressional Record from 1994 forward, committee reports, and House and Senate documents from 1995 forward, selected committee prints from 1997 forward, and even many congressional committee hearings from 2001 forward as well as many from congresses. Some Boolean operators are available on GPO FDsys searches; phrase searches should be surrounded by quotation marks. As GPO FDsys documents are available in text and PDF formats (PDF stands for portable document format and looks just like the printed copy), you can print out most of the documents you need to compile a paper based legislative history. Moreover, using Adobe Acrobat Suite software (the fee-based software, not the Acrobat Reader you can just download) PDF documents can be indexed, highlighted, book-marked, and manipulated in ways so that a near-entire legislative history can be downloaded with portions highlighted and book marked.
You can also assemble a federal legislative history electronically using LexisNexis research software or its sister service Lexis Advance, Lexis has Boolean operators, segment searching, and is able to search across congresses or an individual congress. The Lexis Cong. Record fil goes back to 1985 and its BLTRCK and BLTEXT files go back to 1989. The Lexis CMTRPT file (committee reports) goes back to 1990 and its CMTPRN file (selected committee prints) goes back to 1995. It also has Federal News Service (FEDNEW file) transcripts and testimony of selected congressional hearings from August of 1988 forward. The CIS Index/Abstract service (CISINX) and the CIS Legislative History service (CISLH), discussed above, are also available on Lexis from 1970 forward. Lexis has other relevant information as well, and most of these congressional resources and the above mentioned files can be searched and documents downloaded and assembled into an electronic legislative history. Direct linking to documents on Lexis.com is possible, but the links may change over time. 

Westlaw and WestlawNext have extensive legislative files that can be used to compile electronic federal legislative histories. Westlaw's LH file, discussed above, has selected committee reports that directly relate to public laws from 1948 to 1989 and all committee reports from 1990 forward. It also has the Congressional Record (CR) from 1985 forward and State Net's federal bill tracking and bill text services (BILLTRK-OLD, CONG-BILLTXT) from 1991 to the present as well as selected committee hearing transcripts and prepared testimony (USPOLTRANS - 1994 forward, USTESTIMONY - 1993 forward and CONGTMY - July, 1995 forward). Westlaw has Boolean operators, field searching, and the ability to search across congresses. From 1974 to the present Westlaw public laws has links to selected committee reports and other related legislative history documents. It's premium Statutes service includes PDF copies of statutes from 1789 to 1972, and its Graphical Statutes includes the text of prior versions and time frames of U.S. Code sections from 1996.

There are other electronic sources for compiling federal legislative histories including the extensive files on CQ Congressional Roll Call CQ.com. CQ has news services as well as committee schedules, committee markup summaries and extensive archives back to 1989 with bill tracking, bill texts, committee reports and Congressional Record files. CQ also links to many remarks on legislation in the Congressional Record that is not noted by other services. The CQ Weekly Report, the CQ Annual Almanac (not available electronically) and other CQ news services are also extremely valuable in obtaining an understanding of legislative measures. 

Of course, House and Senate committee Web pages frequently have committee hearing testimony and transcripts (especially on the House side) back to the 105th Congress (1997). However, there is no guarantee that committees will retain information from a previous Congress. Information on these Web pages is provided in LLSDC's Legislative Source Book under Quick Links to House and Senate Committee Documents and Hearings. You can generally find a link to a specific hearing or witness statement to add to a legislative history, but the search capability is limited and generally depend upon your browser's "Edit/Find" functions.

In addition to official government testimony and transcripts of congressional hearings there are unofficial transcripts published selectively by the Federal News Service (FNS), CQ Transcripts ( formerly by Federal Document Clearing House or FDCH - now via Morningside Partners), and audio or video recordings from C-SpanArchives.org and CapitolPulse.com. Other commercial vendors mentioned above use FNS and CQ Transcript services for their testimony (which are generally complete) and transcript files (which are selective).
