Discusses the archives of Britain's Labour, Conservative, andLiberal parties, including their formation, acquisition policies,holdings, organization, and relationship to the parties. All threearchives contain substantial amounts of records, cataloged and easilyaccessible, in well-organized repositories - an accomplishmentcompleted largely without government intervention. The LiberalParty, because it is the smallest and has experienced the mostdisunity of the three major parties, did not develop its archives untilthe mid-1980's, with most of its records dating from since WorldWar II. The other two archives cover the entire 20th-century historyof their parties. The level of organization found in the archivesreflects the British political system itself, which discourages smallparties and intra-party fragmentation.
