A project has been conducted to improve access to the online services of a major university library by implementation of hypertext interfaces to a variety of information resources including the online public access catalogue (OPAC). The main technical issues explored were:
evaluation of searching behaviour and information needs of a specific number of key groups of library users;
prototyping and testing of hypertext interfaces including graphical and pictorial user interfaces for library systems, and the move to personal computer (PC) type environments for library users;
standard generalized markup language (SGML) markup of library catalogue and other records for use with hypertext. The interfaces have been evaluated in relation to the user specifications.
Several SGML document type definitions (DTD) and parsers have been produced and demonstrated, navigation in library catalogues along hypertext links can be demonstrated, and user interface prototyping based on NETSCAPE has been undertaken as a new development.
The project improved access to the online services of a major university library by implementation of hypertext interfaces to a variety of information resources including the online public access catalogue (OPAC). A number of groups of specific users have been identified and for each a detailed user requirement specification, based on information needs in relation to use of online resources, has been formulated. Hypertext interfaces to suit these specifications have been designed and developed. Issues such as language independence, the move to personal computer (PC) type environments for library end-users, graphic user interfaces (GUI) versus VT100 type interfaces and standards for data markup and hypertext are to be examined and evaluated.
The PC based interfaces will be widely applicable given both the increase in use of PCs in place of dedicated terminals and the increase in remote users of OPACs. HYPERLIB enjoys a considerable reputation both for making library information significantly more accessible without heavy cost implications and for the way it went beyond its project parameters to implement an acclaimed OPAC on the World Wide Web. Furthermore, the non-graphic interfaces developed using the VT100 subset can easily be implemented on existing systems.
