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: 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
