Members of Congress can request written reports from experts, and these are published as Committee Prints. Prints are an excellent resource for statistical and historical information, and for legislative analysis. The subjects of the Committee Prints vary greatly due to the different concerns and actions of each committee.
Some committees, especially in the House, issue a Hearing Memorandum, which often contain a statement of the purpose of the hearing, witnesses, background information, and a short bibliography. Look for these from 2004-2011 in ProQuest Congressional in the Committee Prints & Misc. Publications database.
