- Internet users often get discouraged at the low friendliness of library OPACs, especially when comparisons are made with the facility of use of other information resources on the Web. No doubt this problem has to be solved urgently. Use OPACs are not only outdated, but also there is much diversity of systems, that together form a tortuous path in which consultation software library catalogs do not appear as desired help, but each is an obstacle more inside a maze. The problem is becoming apparent due to the fact that today it is possible to connect online to more and more OPACs. In this paper we support the possibility of widespread use of World Wide Web clients -a single, standard- like interfaces to reach, directly or indirectly, through the Internet, to the management programs of bibliographic databases in our centers. This can be accomplished in two ways: 1) The WWW client application uses existing gateways in the network that convert user queries in Z39.50 requests. 2) The use of web systems features without having to access the portals mentioned, with small programs that act as an interface between HTTP server and catalog database. In the second case, the simplest of the two, the following are essential: a) a web browser, that allows users to formulate queries and manage the display and manipulation of the results; b) a web server, with all the typical features of such software; c) a specific software for each library system, which acts as an interface between the web server and the manager of the catalog database. Perhaps the most interesting of this scheme is to highlight the fact that the elements b) and c) may be implemented at any point in the network, not necessarily in the computer system that manages the library catalog, which makes it possible to design a very flexible telematic architecture. It is also remarkable that all this is possible thanks to the existence of the form functions existing in the HTML language since its second version. Item b) sends the data fed in a) to c). The cycle ends with the data flow in the opposite direction.
