ARLIS/UK & Eire has developed a thorough and practical strategy regarding the national provision of art serials in libraries. The keystone of this strategy is the ARLIS Union List of Art Periodicals, shortly to appear in its fourth edition. Titles of new serials are noted in the ARLIS News-sheet. Data in the Union List facilitates co-operation between, and co-ordination of the holdings of, different libraries, and is used in particular to identify those libraries which are the only locations for specific titles. ARLIS is determined that all art journals covered by the major indexes and abstracts are accessible in the U.K. and Eire; at the same time, the attention of publishers of indexes will be drawn to serials which are not indexed. ARLIS is represented on the advisory boards of major indexing and abstracting services, and in addition has completed a survey of ‘in-house’ indexes maintained by different libraries. Further developments are likely to depend, not merely on the co-operative efforts of members and on co-operation with other bodies, but also on the availability of funds and, hopefully, of a researcher.
