The research project Digital Archive of Belgian Neo-Avant-garde Periodicals (DABNAP) aims to digitize and analyse a large number of artists’ periodicals from the period 1950–1990. The artistic renewal in Belgium since the 1950s, sustained by small groups of artists (such as G58 or De Nevelvlek), led to a first generation of post-war artist periodicals. Such titles proved decisive for the formation of the Belgian neo-avant-garde in literature and the visual arts. During the sixties and the seventies, happening and socially-engaged art took over and gave a new orientation to artist periodicals. In this article, I wish to highlight the challenges and difficulties of this project, for example, in dealing with non-standard formats, types of paper, typography, and non-paper inserts. A fully searchable archive of neo-avant-garde periodicals allows researchers to analyse in much more detail than before how influences from foreign literature and arts took root in the Belgian context.
