Title
CD-ROM sources in the reference collection : issues of access and maintenance
Source
Reference librarian. 1990, no.29, S.77-91
Year
1990
Abstract
Contribution to an issue devoted on the weeding and maintenance of reference collections. CD-ROM has become part of the library universe and increasing numbers of libraries are considering the acquisition of reference tools in the new format. Issues of evaluation and selection, hardware purchase, and budget are primary concerns in this decision. Many aspects of day-to-day maintenance and access to CD-ROM sources must also be considered in the evaluation process. These issue-space, security, the care and feeding of hardware and software, reference assistance, staffing and staff training, and user instruction are vital to the success of CD-ROM in the library. Focuses particularly on literature about training for staff and users.
