Interest Groups and Lobbyists: Sources of Information

Prepared for Members and Committees of Congress

Lobbyists and interest groups play an active role in the American legislative process. Information
on lobbyist registrations and on interest groups in general is available from a variety of online and
printed sources, including files available for public inspection.
This report is a guide for locating governmental sources that maintain files on lobby groups, their
registrations, and finances. Also included in this report are nongovernmental sources that offer
background information on the lobbyists and interest groups who focus on legislation in
Washington. Many of the works listed are available to congressional staff in the Jefferson and La
Follette Congressional Reading Rooms, CRS research centers, and to constituents in large public
and research libraries.
This report will be updated yearly or if current lobbying regulations are changed by Congress.
Current legislative proposals related to lobbying disclosure are discussed in CRS Report
RL34008, Lobbying Reform Legislation: Side-by-Side Analysis of Lobbying Provisions in S. 1 th
and H.R. 2316, 110 Congress, by Jack Maskell.

The Lobbying and Disclosure Act of 1995 (LDA), P.L. 104-65, 109 Stat. 691 (1995) as amended
by the Lobbying Disclosure Technical Amendments Act, P.L. 105-166, 112 Stat. 38 (1998),
requires lobbyists to register with the Clerk of the House and Secretary of the Senate and to make
semiannual reports of their activities. These reports identify the name of the registrant (firm or 1
individual), client, and broad issue area in which lobbying was carried out.
Both the Clerk of the House of Representatives and the Secretary of the Senate receive and
maintain the lobby registrations and semiannual disclosure reports of those filing as lobbyists
under the LDA. The offices also maintain the records previously required under the Federal
Regulation of Lobbying Act of 1946. That law was repealed by the LDA.

1 Aclient” is defined under LDA as any person or entity that employs and compensates another person to conduct
lobbying activities on behalf of that person or entity. A coalition or association may also be listed as a client. LDA does
not require information on the specific membership of these groups to be disclosed. Some observers suggest that this
could allow entities to shield their lobbying activities through the use of ostensibly separate, independent coalitions and
associations. Consequently, when the client is an association or coalition, the interested parties may not be identified in
LDA disclosure reports. For further information, see CRS Report RL31126, Lobbying Congress: An Overview of Legal
Provisions and Congressional Ethics Rules, by Jack Maskell.
