There is biographical information available of more than 2,500 individuals active in the liberal movement.

The Liberaal Archief also published a Concise bio-bibliography of prominent liberals from 1830-1990. This reference work contained in its original book form information on 1,600 individuals who were or still are active in the liberal movement in Belgium: politicians, journalists, publicists, writers, and scholars.

A fully updated (May 2006) online version is available in the Dutch section of this site, with information on more than 3.000 names.
