Abstract

A CD-LAN is not necessarily the best solution for a library and will not access every electronic publication which a library may want. An alternative for providing concurrent access is to mount journal citation files on a local library system. This involves loading tapes of periodical indexes or other publications onto the local library system and offering access to them through the OPAC. Discusses journal citation modules; online enhancement; the hybrid electronic publications strategy; costs of online database services, standalone CD-ROM, CD-LAN and journal citation modules. Offers a comparative cost analysis via case studies of ABI Inform, Applied Science and Technology Index, Biological Abstracts; INSPEC, Math-Sci, NTIS, and Science Citation Index for each of the options online and by CD-ROM, CD-ROM LAN and a journal citation module on a local library system

Abstract

Study was undertaken by Information Systems Consultants, Inc., Washington DC, to determine the current state of online patron access catalogues, with emphasis on the degree to which access has been extended beyond that available in card, microform, and early patron access online catalogues. The methodology used was similar to that used in an earlier report. All of the library automation vendors of both multi user systems and micro based systems were sent a copy of the latest version of the catalogue portion of the model RFP (request for proposal) for an integrated online library system which was developed for the study described in the last reference. The vendors were asked to respond as if it had been sent by a potential library customer. A matrix with the raw data is presented for both multi user systems and micro based systems along with the RFP. A brief description of each vendor is followed by a tabulation of the RFP responses and concluding comments by the author

Abstract

Discusses the problems of using a CD-ROM drive with a network. Many CD-LANs being installed are commercially available products, but there are a number of vendors offering software or hardware components that can be used to design and implement CD-LANs. One reason in-house development of CD-LANs has not been more common is that most LANs don't handle CD-ROMs very well. Describes the operation of a CD-LAN considering topologies, operating systems, low-cost LAN software products, jukebox versus server, high-density PCs, multi-user PCs, gateway access, caching, CD-LAN performance and CD-ROM servers for large CD-LANs. Assesses turnkey systems from Meridian Data, Online Computer Products Inc. EBSCO and SilverPlatter
