The archival section with a total length of more than 2,600 meters constitutes with the library the main part of the collections of the Liberaal Archief. Archives of individuals active in the liberal movement are kept as well. Records of more than 1,000 local associations in Flanders are available. Regarding international liberalism the Liberaal Archief keeps documents of the Liberal International and the Mont P lerin Society.
Every effort is made to make the archives accessible for research.
Considering the rapid increase of the collections, archives are made quickly accessible through storage lists. Inventories are made in a second phase. A survey of the published inventories is available in the section Publications. Archives may be donated or entrusted. Restrictions concerning consultation of the deposited archives can be included by mutual agreement.
