Exhibition catalogues, in spite of being an important aspect of art documentation, too often escape the notice of both libraries and bibliographies; their existence may be unsuspected and they may disappear without trace. With support from the British Library, ARLIS/UK & Eire is currently conducting a comprehensive survey of exhibition catalogue production and acquisition in England over a period of twelve months; the survey involves the active participation of art librarians throughout the country as regional co-ordinators and local collectors, and it constitutes a study of the feasibility of a permanent collecting network. Such a network is desirable, not least to supplement the national system of legal deposit and to provide data for inclusion in the British National Bibliography.
