Description
The ADP-system LIBRIS-II is described with emphasis on its network structure. The connection of 10 libraries within the organization under the National Swedish Board of Universities and Colleges (UHÄ) and four other libraries is outlined. The coverage of acquired literature in the connected llbrarles is discussed, as well as the extension of the coverage which is achieved by a decentralized reporting of accessions in a large number of other Swedish research and special libraries to the Royal Library which submits centralized input to the system. Three possible models are presented how to offer access for searches to LIBRIS outside the family of LIBRIS-libraries through 1) the existing programmable terminals, 2) dial-up ports in the front-end computer, 3) packet-switching networks such as SCANNET.
Figures on data traffic in the network as weIl as error statistics are given, and possible conclusions are drawn. Variations in how the central processing unit is affected by LIBRIS usage are illustrated and analyzed. Response time and factors influencing on the response time are discussed. Facilities to indicate the system status at the terminals are described. The possibility to diminish (minimize) effects of system breakdown by indicating when the system is open again is emphasized. The expansion and the changeover to another computer and the problems involved in this work is also discussed.
