Abstract

As a solution for networked information retrieval the ISO has adopted the SR/Z39.50 protocol. Debate however continues, particularly as regards OPAC, on the relatice merits of Z39.50 and the facilities afforded by the WWW, which based on the http protocol. Examines the features of these 2 solutions for OPAC, and also describes the ARCA project, set up in 1995 with finance from the EC Libraries programme to implement the Z39.50 protocol
