Congressional Research Service

This guide will provide a brief overview of the CRS and some suggestions for locating its reports. It should be noted that the CRS started maintaining a publicly accessible research website in 2018.

What is the Congressional Research Service?

The Congressional Research Service (CRS):

  • is the non-partisan policy research arm of the United States Congress
  • has been a component of the Library of Congress since 1914
  • produces documents at the request of and for the use of members of Congress
  • provides Congress with research and objective analysis on a wide variety of topics
  • is often regarded as a source second to none, because of its non-partisan, timely, and accurate information
  • CRS staff also provide testimony in Congressional hearings, conduct seminars, briefings, and institutes for Congressional members and their staff
  • over the past two decades has even provided assistance to members and staff of foreign legislative bodies

Document Types

The CRS produces a number of types of documents.


The most commonly requested documents are reports.

  • The purpose of a report is to clearly define the issue in the legislative context.
  • Reports may take many forms including policy analysis, economic studies, statistical reviews, and legal analyses

Issue Briefs

A second type of CRS document is the Issue Briefs. These short documents include:

  • issue definitions
  • background and policy analyses
  • legislation passed and pending
  • a bibliography of hearings, reports, documents, and other congressional actions
  • a chronology of events
  • reference sources

Other Documents

Other document types include:

  • Appropriations Reports (usually released as a Long Report)
  • Electronic Briefing Books
  • Info Packs
  • Congressional distribution memoranda

Finding CRS Publications in the Government Documents Unit

While CRS publications are rarely distributed to federal depository libraries, we do have a commercially published set:

  • Title: Major Studies and Issue Briefs of the Congressional Research Service
  • Dates covered: from 1916 - 2004
  • Format: microfilm
  • Indexes: some, but not all indexes, to the microfilm

Finding CRS Publications Online

In the past, the Congressional Research Service (CRS) did not provide direct public access to its reports, requiring citizens to request them from their Member of Congress. Some Members, as well as several non-profit groups, would post the reports on their websites. The CRS began publishing reports online in 2018. Below are major online collections of CRS Reports.
