    Abstract
    The primary objective of the present study was to exmine whether readers conducting bibliographic searches in ALEPH - Israel's research library network - tend to search only within the OPAC of the library within which they are working or whether they access the remote OPACs of other libraries. The ALEPH network has a dezentralized database. Therefore, it was possible to examine this question because each library has its own access code and each database can be searched separately. The data were collected by means of a one-page questionnaire lefr beside each terminal in the library of the Graduate School of Library and Archive Studies of the Hebrew University of Jerusalem during an entire academic years. results of analysis of the data collected in this survey are presented in 6 tables

    Abstract
    CD-ROM databases are finding a permanent niche in libraries and librarians are trained both to use each new product and to keep abreast of changes in them. From the library user point of view it is possible to dial into or remotely access CD-ROM databases. Discusses the use of the communications software pcAnywhere, examines the benefits to users and libraries of remote access, and lists other areas which might be of interest to learning resource centres in regard to CD-ROM services

    Abstract
    Expanded hours of access and the reduction of peak system loads are often cited as advantages of remote access to OPACs. This argument is based on the assumption that remote users search OPACs when libraries are closed or when there is low internal use. The study tested this assumption by performing a transactional log analysis of the remote and internal use of the OPAC at the Research Libraries of the New York Public Library. Analysis showed that pateerns of remote and internal use differed greatly. A large part of the remote searching occured when the Research Libraries were closed. Compared to internal searching, remote searching was distributed more evenly over the course of the day and the week. Results show that remote access expands the hours of use of the Online catalogue and has potential to reduce peak system loads at the Research Libraries

    Abstract
    Computer and communications technology is having a profound impact on libraries and the way in which they serve their users. Discusses online catalogues in libraries, the development of the Internet and OSI, and the development of search and retrieve (SR) protocols to allow standardized access to library catalogues across communications networks. Considers the deployment of SR protocols, problems with interoperability of clients and servers, interlibrary loan possibilities of SR protocols, and the feasibility of electronic document delivery

    Abstract
    The function of the W3, like that of Z39.50, is to offer access to networked information, and they appear to have similar client/server architectures. However, libraries need both because of the W3's lack of support for the advanced search, retrieval and management facilities that are expected of modern OPACs and are offered by Z39.50. Current research is involved in developing hybrid W3/Z39.50 services

    Abstract
    Looks at the services offered by academic OPACs. Describes the services provided by Harvard Online Library Information System, University of California MELVYL Catalog, Stanford University' SOCRATES, and Princeton University Library. Many libraries now offer dial-up and/or Internet access to their OPACs

    Abstract
    Networks allow different users from outside the library to have remote access to library catalogues. These remote users may face problems that differ from the OPAC users' in the library. They may not be comfortable with the computer technology and may not be familiar with the OPAC of the library. Libraries should offer different support services from those provided to on-site users. These users need technical advice as well as special instruction aids and guides to lead them to the information they want to retrieve
