Summary
Interest groups, including those who actively lobby, continue to play a role in the
American legislative process. After years of congressional efforts to improve disclosure
of interest groups, the Lobbying Disclosure Act (LDA) of 1995 (P.L. 104-65) and the
Lobbying Disclosure Technical Amendments Act of 1997 (P.L. 105-166) were signed
into law on December 19, 1995, and April 6, 1998, respectively. Both laws seek greater
disclosure of interest groups’ activities and more accuracy in reporting their spending.
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 provides a list of directories and online services that offer background
on the interest groups and lobbyists who focus on legislation in Washington. Many of
the works listed are available to congressional staff in the CRS reading room and
research centers and to constituents in large public and research libraries. Also included
is a list of governmental and nongovernmental offices that maintain files on lobby
groups, their registrations and finances, and other similar details. Web addresses are
given where available. This report will be updated yearly.

Selected Electronic Resources
New lobby registrations were listed in the Congressional Record until January 1996.
That practice ended after the enactment of the Lobbying Disclosure Act of 1995 (LDA),
which no longer required new registrations to be published in the Record. However,
information on pre-1996 registrations is still available through several online services
providing historical access to the Congressional Record. Brief descriptions of selected
Internet sources are provided in this section, with pertinent contact information.
