- Abstract
- Discusses the advent of software packages (termed front end packages) which are installed on PCs or Macintosh machines and provide the user with an interface to online databases. The packages involved usually provide graphical user interfaces (GUIs) and are dedicated to particular online systems. Focuses on KR ProBase which was introduced by Knight-Ridder in 1995 for information specialists to search DIALOG and DataStar (though not yet with a single interface). Describes the features of this product. Concludes with a brief discussion of the alternatives to host specific software packagaes, Z39.50 and Web browsers such as Netscape

- Abstract
- Observes that whether in academic, special, or public libraries or on commercial online systems, CD-ROM, the online catalogue, or the Internet, certain end user errors crop up repeatedly. Details the main errors, which include input errors, errors arising from confusion in the face of different interfaces and screen designs, Boolean logic errors, term errors, conceptual errors, and errors due to the fact that users do not read instructions. Concludes that systems must solve the trivial errors automatically, but user instruction librarians must help solve the more complex problems

- Abstract
- Considers some of the human factors in online interaction and Internet use. Discusses the following: users' need for help from libraries and librarians, given the difficulties people continue to have in accessing and using networked information; the challenge of user demands for speedy delivery of information and documents; the trend towards 'humanizing the net' through chat rooms and social agent interfaces (such as Microsoft's Bob); and the problems for libraries of users using the Internet for trivial or pornographic purposes

- Abstract
- In 1973 F. W. Lancaster published the first textbook about online information retrieval (with E. G. Fayen). That text and his later writings and books on the topics relating to online searching set the precedent for many books to follow. His early work also advocated many changes to the state-of-the-art systems and anticipated many of the characteristics of modern online information retrieval systems. Although the basic underlying structure of modern systems is still similar to what Lancaster wrote about thirty years ago, many of the changes he advocated have occurred. From an era of bibliographic databases on command-driven systems searched by library professionals, online systems have evolved to have friendlier interfaces, include full texts or links to full texts, and are targeted to the end users of the information. The information industry has evolved, as have the online search systems and tools that are so commonplace today.

- Abstract
- Describes the online end user search service, FirstSearch, provided by OCLC, noting the ways it has developed since its launch in 1991, and the extent of its use in libraries worldwide. Focuses on an important new aspect of the service, the availability of the full text in ASCII format of many of the articles cited in the database, for ordering, viewing and downloading. Also discusses the value of FirstSearch to interloans departments, the costs of the service, enhancements in the searchability of the databases and in the interfaces provided for searching, and the variety of uses to which libraries are putting the service

- Abstract
- Outlines 3 generations of online searching: to 1981, when personal computers became ubiquitous, when searching was done from dumb terminals by intermediaries; from 1982 to 1991, when through the use of the PC, faster transmission speeds and the advent of ASCII full text, specialized end users joined intermediaries in the exploitation of online; and a generation characterized by multimedia PCs, higher transmission speeds, ASCII and 'image' full text databases, the invlovement of the general end user. Reviews the evolution of these 3 generations in 4 specific areas: content/databases; people and organizations involved; the places people search; motives for using online; and search engines and interfaces used

- Abstract
- Report of a survey 96 (out of 119) US and Canadian member libraries of the Association of Research Libraries (ARL) to determine their use of on-line and CD-ROM data bases, including OPACs. 4 catalogues were identified: on-line mediated searching (97%); CD-ROMs (96%); end-user on-line searching (45%); and locally mounted magnetic tapes (37,5%). The latter option is expected to be the most widely used option in the new future. Although CD-ROM caused some migration from on-line, most migration was from printed sources to CD-ROM. Tables show: on-line hosts most used for intermediary on-line searching; on-line data bases most after searched by intermediaries; end user on-line systems offered by most libraries; the 20 most popular CD-ROM data bases; and the 8 magnetic tape data bases accessible on OPACs

- Academic and special research libraries in the US and Canada access on average 7,4 online systems. This probably doubles or triples when including CD-ROMs and locally loaded databases. Examines the many ways in which online versions of databases can vary on different systems. Discusses the differences of updating, dates covered, price, subfile structure, field subdivisions, content or inclusion, support features and system search features. Provides statistics on these differences

- Examines why online systems and CD-ROMs are producing a greater need for bibliographic instruction. Most online systems and CD-ROMs operate with the same software developed for the first online systems 20 years ago. Innovative search techniques such as natural language have spread from inhouse databases to the commercial online and CD-ROM environment. Personal Librarian and Westlaw Is Natural represent the online second generation. Discusses Personal Librarian; CD-ROM products; online expansion and DIALOG and Personal Library Software

- Abstract
- The only monitoring of educators is performed by their internal sense of right and wrong. Following the aggred terms of system contracts, selecting the most appropriate systems for students, keeping up to date with system features, and instilling ethical behaviour in students are at the core of ethics for online educators

- Abstract
- WESTLAW is one of the first major commercial online systems to embrace both natural language input and partial match searching. Provides a backgroud to WESTLAW. Explains how the WESTLAW Is Natural (WIN) search engine works. Some searchers find that when searching with commands and Boolean logic, results differ drastically from those produces by searching with WIN. Discusses exact match Boolean logic search engines

- Abstract
- Online offers the advantage over CD-ROM and locally loaded databases of being able to search several databases simultaneously. However, even when different databases have common fields, they may be named differently. This is improving, particularly throught he efforts of Mead Data Central and DIALOG. Discusses searching single databases; 2 ways in which online systems standardise fields; the lack of standardisation in the field tag SF=; Dialog's standardisation; generic field designs; standardisation of field content and NEXIS and uniform segmentation

- Abstract
- Discusses a number of trends in the provision of commerical research online systems to end users, as opposed to professional intermediaries. The trends highlighted include: Web versions of, for example, FirstSearch and EBSCOhost; end user access via the library, which cushions the user from direct paymant for use; the integration of information sources in specific subject areas; the rethinking of proprietary software solutions; and the provision of specialized products with a very specific customer focus
