- 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
- 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 variety of search services supporting library reference functions offered by the RLG in the USA. The best known of these is RLIN, the massive bibliographic database and related services originally developed for shared cataloguing. In the last few years RLG has added CitaDel, an online search system that provides access to indexing/abstracting databases; and Zephyr, a Z39.50 server that amkes the RLIN and CitaDel databases searchable through a library's online catalogue. RLG also offers document delivery connections, including Ariel and Internet based document delivery software, for a full complement of online reference support for academic and public libraries

- Abstract
- Reports on a survey of ARL (Ass. of Research Libraries) members in the USA in 1994, which sought to find out the electronic reference services that are offered by these libraries and how the services affect reference staff, the expectations of users, and user instruction. The services covered include CD-ROM, intermediary online searching, end user online (e.g. FirstSearch), tape loaded databases and user access to the Internet, including electronic mail facilities. Highlights the additional workload the provision of these services involves, and the sometimes unrealistic expectations of users especially with regard to Internet resources

- Abstract
- State of the art review of the development of full text databases, encompassing: types of commercially available full text databases; online systems for full text databases; CD-ROM databases for full text databases; full text databases on magnetic discs or tapes; creation of full text databases; searching and display requirements for full text searching and software. Concludes that bibliographic information services without full text support solve only half of the retrieval problems

- 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

- Looks to the future of traditional online services, in light of the rising use of the WWW, which brings authors or publishers and readers directly together, without the intermediary role played by online vendors. Gives examples of changes in ownership of online services in the last half of 1997, and notes that the changes all suggest that online vendors must nkow their best markets and stick to them. Concludes that many online vendors will survive but in ne configurations and often with new owners

- 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
- Knowing the inner workings of an online or CD-ROM system may help to explain strange results, improve search strategies and aid trouble shooting. Discusses search strategies for Boolean and for statistical search engines; how DIALOG's Boolean system treats blank spaces; default settings for searches; how DIALOG defines words; stop words; automatioc truncation and automatic substitute features

- 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
- The study investigated the factors of response time, coverage, content and cost in CD-ROM and online versions of 2 popular databases: SilverPlatter Information Ins.'s and DIALOG's version of Psychological Abstracts (PsycINFO and PsycLIT) and Sociological Abstracts (Sociofile and Sociological Abstracts). Results confirm that, though the databases may be similar, significant differences do exist. Specifically, online searching gives a more consistent or predictable response time and yields greater currency, consistency and coverage

- Abstract
- 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

- 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
- 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
