Web OPAC interfaces: an overview

Web-based online public access catalogues (OPACs) began to appear in the la te 1990s and many libraries are currently considering implementation. As ca talogues, they demonstrate advances on traditional OPACs, especially in ter ms of remote access by users and their potential to integrate many document types and sources via a single interface. This paper considers some of the features and functions of Web OPAC interfaces. As yet, very little evaluat ion of systems and users has taken place and until more such literature app ears, a general approach to products available is considered to be of value . Six popular Web OPAC interfaces in use in UK academic libraries (Talis, I NNOPAC, WebCat, Voyager, GeoWeb and ALEPH) have been examined with an overv iew of the functions offered via those interfaces. A checklist has been dev eloped as an indicator of the important features and functions offered.
