Building on the precedent established by the Kunstakademiets Bibliotek and RILA, Nordic countries are for a trial period of three years contributing bibliographic records to the BHA, via the latter’s Scandinavian editor in the U.S.A. Several institutions are involved; the selection and preparation of records for the BHA can usually be done in conjunction with work already undertaken by the institutions concerned, in some cases for national bibliographies. Records include abstracts, which should ideally be provided or approved by the authors. Only a selection of material can be cited in the BHA; it is important that its international role should be complemented by national bibliographies. Although Nordic libraries can subscribe to the BHA in its printed form, online access is inhibited by financial considerations; a CD-ROM version would be most welcome. It is hoped that this three year experiment in co-operation will be judged a success, and that funding to enable it to continue will be forthcoming; a crucial test of any form of international co-operation is whether respect for national traditions outweighs any desire for excessive standardisation.
