Digitized versions of internal working papers from the various committees of the United States House of Representatives and Senate, from 1830 to the present. Committee prints include a wide variety of publications approved and issued by committees or portions of committees, such as majority or minority staff. Prints issued by only a portion of the committee are normally identified as such on the cover.

A committee print can contain anything relevant to the legislative and oversight functions of Congress. The print content varies widely from committee to committee, and over the course of time the function and format have been inconsistent. Examples of committee print content include: research papers by committee staff, Congressional Research Service experts, or outside consultants; committee rules and calendars; compilations of laws; transcripts of markup sessions or other proceedings; and legislative descriptions and analyses. Many committee prints may best be described as reports, but these reports should not be confused with reports that are numbered as official House or Senate reports.
