Title
¬The reference world expands : new options for answering questions
Source
Computers in libraries. 18(1998) no.5, S.62-65

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
