Congressional (ProQuest) This link opens in a new windowProQuest Congressional provides abstracts and indexing for all hearings from 1970 to present. The BASIC search performs a search of the abstracts and indexing for hearings. To search the FULL TEXT of these selected hearing transcripts you must start from the ADVANCED search screen and use the pull-down menu to select "ALL FIELDS INCLUDING FULL TEXT". The "Retrieve Selected Testimony" feature offers access to witnesses' written statements and selected hearing transcripts from 1988 to the present, provided by various third parties who cover Capitol Hill. Because there is no requirement that congressional committees publish hearings, some hearing transcripts are transferred to the National Archives where Senate hearings remain for at least 20 years and House hearings for 30 years. Hearings that are not published due to national security concerns may remain sealed in the National Archives for up to 50 years before they become accessible to the public.Coverage begins 1970.
