Materials prepared for the use of committees are published as committee prints. They provide documents legislators consulted while considering bills.
Results of some Congressional investigations are published as House or Senate Documents and occasionally are useful as sources of legislative history.
The Committee to which a bill is referred will hold public hearings if the bill is important or controversial. Written testimony may be submitted by various public officials, experts and private individuals who might also be allowed to give a brief oral summary of their testimony and be interrogated by members of the committee. A transcript of the hearings is made and is often printed for public distribution. Hearings on legislation may be held during several Congresses before the legislation is passed.
Prints, documents and hearings contain investigations, white papers, background and other research materials that the committee members considered when working with a bill. These are the "inputs" of the process. Review the materials the committee considered to reveal what information they were reacting to when drafting their recommendations.
For more information, consult the sources in the "For more detail..." box on the Legislative Process tab.
