- Abstract
- Reports a survey of all academic members of the Association of Research Libraries in the 4th quarter of 1997 which examined how academic libraries incorporate electronic information sources into their reference activities and the effects on libraries services. There was a response rate of 68 per cent, Compares results surveys carried out in 1991 and 1994. The survey covered: numbers of computers access options (intermediary, end user online, CD-ROM locally loaded databases or those accessible through the library catalogue and the Internet. There is a trend away from print resources, particularly indexing and abstracting materials, and away from CD-ROM LANs and local loading of databases towards remote online resources

- Abstract
- There is no generally agreed definition of reference publishing in the industry today. Identifies attributes which are more likely to be associated with reference publishing than with publishing of the non-reference sort, including comprehensiveness, objectivity, authoritativeness, strong reliance on brand names, a disinclination to pay royalties and the common strategy of internal product development. Reference publishers conceive their publications as existing in a larger information context, providing 'background'. discusses the use of computers in reference publishing, both in production, and in publishing itself, on CD-ROM or online. Argues that current CD-ROM reference works are not true reference works as they are used generally as a goreground activity, not as a source of background information. Sees the future of CD-ROM publishing as entertainment publishing and predicts that reference publishing will go online

- Abstract
- Describes the advantages of CD-ROMs over printed and on-line sources: large storage capacity, relative cheapness and minimum instruction required to undertake searches. Identifies 5 main criteria from the literature which should be considered when introducing this technology into reference libraries. Cost, currency and contents should be considered when comparing their usefulness with other media. At present, CD-ROMs offer the most efficient service when used in conjunction with both printed and on-line media

- Abstract
- The growing number of networked information resources and services offers unprecedented opportunities for delivering high quality information to the computer desktop of a wide range of individuals. However, currently there is a reliance on a database retrieval model, in which endusers use keywords to search large collections of automatically indexed resources in order to find needed information. As an alternative to the database retrieval model, this paper outlines the classical digital library model, which is derived from traditional practices of library and information science professionals. These practices include the selection and organization of information resources for local populations of users and the integration of advanced information retrieval tools, such as databases and the Internet into these collections. To evaluate this model, library and information professionals and endusers involved with primary care medicine were asked to respond to a series of questions comparing their experiences with a digital library developed for the primary care population to their experiences with general Internet use. Preliminary results are reported

- Abstract
- The Multimedia Encyclopedia of Mammalian Biologie CD-ROM was published by McGraw-Hill in Sept 92. It has been designed for use primarily at undergraduate level. Text, images, sound and movie clips and numerical information (data) can be accessed on the disc. In this article the concept of Resource Policy, allowing priority to be given to any one of these media types, is described. The principal methods of using the Encyclopedia (Browse and Search) are described. The working of the 4 hierarchical Browsers is outlined, together with the operation of 'Linked Mode'. The methods use to index the data to the Browsers is also discussed and examples of how the disc may be used are given. The text search features available on the disc are also described. These include simple text search, using Boolean operators, and the ability to search the disc not according to the text itself, but using the indexing structures which underpin the Browsers. Attention is drawn to the implications of this approach for structuring information and upon the costs of developing commercial titles

- Abstract
- Reviews the current market for CD-ROM databases with particular reference to the online versus CD-ROM versus print debate. Concludes that the most likely scenario is a steady convergence of technologies, at least until the end of the century. Review the current and the most likely future developments in the area of CD-ROM database contents, software, hardware, and marketing. Concludes that users will choose databases on the basis of such factors as: ease of use; power of use; storage and delivery capacity; quality; functionaliy; timeliness; overall appeal; and real cost, not just price. Lists the most likely candidates for successful CD-ROM database development; not yet available. Concludes that Windows user faces will steadily replace DOS based systems, but not unless the Windows replacements are truly better and not just different. Recommends that both Windows and DOS interfaces be loaded onto the same CD-ROM with each database allowing the user to choose which to use. Reviews likely developments in CD-ROM hardware and marketing strategies

- Abstract
- CD-ROM multimedia encyclopedias have rapidly grown in popularity, purport to be cheaper than their print counterparts, and offer 3 big advantages: speed, keyword searching; and multimedia features. However, CD-ROM multimedia encyclopedias do have their limitations. Explains the hidden costs in their use and sets out their drawbacks which include: they can only be used by one person at a time; they are more difficult to network; provisions of more than one station requires a network software licence; and they require specific skills for which training programmes are necessary. Advocates the use of both print and CD-ROM formats in the school library to enable students to choose that which best meets their needs for a particular assignment

- Abstract
- Considers the issue of point of use user training for users of CD-ROM databases including consideration of whether any such instruction should be provided; whether only minimal instruction should be provided; how library or user type may influence levels of service; and how to balance the reference desk demands in the age of proliferating CD-ROM databases. Concludes that it is unrealistic to expect to place a definite time limit on point of use user training for CD-ROMs, apart from eliminating it altogether. Recognition of the need to balance CD-ROM point of use training with other reference services should help libraries to come closer to the ideal of a prioritized library service

- Abstract
- The large number and variety of online databases in the field of environment sciences and chemistry underlies the need for a cooperative evaluation approach. Presents 2 evaluation criteria, divided into 4 headings; general criteria (size of data source, cost of 1 hour searching, updating of database, availability on other media); chemical relevant criteria (number of chemicals, identification parameters of chemicals, test set chemicals, development of chemicals), environmental relevant criteria (information parameters for chemicals, parameter development); and criteria describing environmental chemicals (use of chemicals, quality of database). A 6 number scoring system is applied to these criteria and the Hasse diagram technique is presented for 19 bibliographic online databases using these criteria. Using this technique, 'good' and 'bad' databases are identified and changes in the database content from 1995 to 1998 can be visualized

- Abstract
- Database usage data from a random sample of academic and public libraries in the U.S. and Canada reveals patterns of use in selected types of libraries. Library users in both public and academic libraries tend to use commercial online databases most frequently early in the week, mid-day, and at times that correspond to the academic calendar (November in this six-month sample.) The mean number of simultaneous users is correlated with the size of the population served and the number of workstations available, but relatively low numbers of users are simultaneously logged on to research databases at all sizes of libraries. A questionnaire sent to these same libraries identified many other factors that might influence database use, including levels of instruction, availability of remote login, placement of a database on the library's homepage, although none of these factors was found to be statistically significant

- Abstract
- An increasing numner of CD-ROM products, as well as online products previously accessible via telnet or other dial-up ooptions, are now being made accessible via the WWW. Discusses the usefulness to the academic reference librarian of Web-based databases comparing them to CD-ROM, print and online reference resources. One of the most important reasons for selecting Web-based databases is the opportunity for remote end-user access, particularly essential for distance education programmes. Describes recent research that shows that whatever the format, there is an increased need for user instruction in the appropriate use of reference material

- Abstract
- Describes an experiment using 48 sixth-grade students to compare retrieval techniques using the print and CD-ROM versions of Compton's Encyclopedia. Four queries of defferent complexity (measured by the numer of terms present) were searched by the students after a short training session. The searches were timed and the retrieval steps and search terms were noted. The searches were no faster on the CD-ROM than the print version, but in both cases time was related directly to the number of terms involved. The students coped well with the CD-ROM interface and its several retrieval paths

- Abstract
- A unique collection of historical material covering the lives and events of an English village between 1400 and 1750 has been made available via a WWW enabled information retrieval system. Since the expected readership of the documents ranges from school children to experienced researchers, providing this information in an easily accessible form has offered many challenges requiring tools to aid searching and browsing. The file structure of the document collection was replaced by an database, enabling query results to be presented on the fly. A Java interface displays each user's context in a form that allows for easy and intuitive relevance feedback
