This study is an attempt to do the following: (1) determine the extent that CD-ROM databases are used by librarians and patrons in Ohio law libraries; (2) define librarian and patron research preferences comparing CD-ROM, print, and online resources; (3) track general trends in law library acquisition of CD-ROM databases; (4) examine the degree of CD-ROM training offered in Ohio law libraries; (5) chart the availability of CD-ROM publications on computer networks in Ohio law libraries; and (6) document librarian opinions concerning the importance of print materials in an environment where duplicate electronic resources such as CD-ROM and online services are available. Research was conducted through a survey mailed to a population of Ohio law librarians. The literature review discusses the general characteristics of CD-ROM databases, the growth in the number of legal titles in CD-ROM format offered annually, and the results of a 1994 survey of CD-ROM usage in New York law libraries. Analysis of the data collected indicates that: CD-ROM is widely and frequently used in Ohio law libraries; it is not used as frequently as print or online resources; there is an increasing trend to offer CD-ROM titles through computer networks to multiple users; librarians endorse retention of print holdings duplicated by CD-ROM; and librarians recognize that CD-ROM is steadily duplicating at least a portion of the print materials in their collections. An appendix contains the survey questionnaire and cover letter, works cited and bibliography. (Contains 14 references.) (Author)
