Since 1970, Indiana University School of Medicine Library (IUSML) has traditionally been a high volume online searching institution. The library recently implemented an end user searching program which includes MEDLINE on CD-ROM. The effect of CD-ROM on online end user and mediated searching is discussed. Comparative statistics are provided by category of search service. CD-ROM has had a dramatic lowering effect on online end user searching and has had little effect on mediated searching. IUSML's experience with CD-ROM technology has been a positive one. Trained end users have become IUSML's greatest asset. 相似文献

Indiana University School of Medicine Library (IUSML) has traditionally been a high volume searching institution. The dramatic effect of CD-ROM on online end-user searching and the negligible effect on mediated searching was reported in an earlier study. This follow-up study reveals that the proportion of mediated searching has been drastically reduced from 94% in 1986/87 to 39% as of November 1989. Mediated searches are declining in absolute numbers as well. End-user searching, by contrast, has increased by 54% percent over the previous year. A related trend is the increased use of CD-ROM by the librarian as an alternative to mediated online searching. These trends are expected to continue as IUSML expands its CD-ROM operation to include other databases. As mediated searching declines, the librarian's role will increasingly include end-user training. 相似文献

The emergence of CD-ROM (compact disc/read-only memory) versions of the MEDLINE database requires experienced MEDLINE searchers to examine assumptions about searching MEDLINE, since some expectations may not be fulfilled by this new technology. When applied to a particular CD-ROM MEDLINE product, the evaluation procedure involves testing assumptions concerning database contents; mechanics of searching; display, print, and download capabilities; and user-friendly features. The extent to which a CD-ROM product preserves and exploits important MEDLINE strengths should be assessed, e.g., the MeSH controlled vocabulary, the designation of major and minor MeSH emphasis, and the use of subheadings. Search software characteristics that affect ease of searching and quality of results also need to be examined, e.g., the ability to truncate search terms and the order of precedence in which Boolean operators are evaluated. A checklist to assist in the evaluation process is presented, including search examples for use in testing search functions. 相似文献

A survey of 131 eastern Washington rural family physicians showed that 59.5% owned a personal computer with a CD-ROM drive. There was an inverse correlation between the physicians' years in practice and computer ownership: 10 years or less (80.6%), 11 to 20 years (72.2%), 21 to 30 years (55.6%), and more than 30 years (32.4%). Those physicians who owned a computer used their CD-ROM for entertainment (52.6%), medical textbooks (44.9%), literature searching software (25.6%), drug information (17.9%), continuing medical education (15.4%), and journals on CD-ROM (11.5%). Many rural doctors who owned computers felt that CD-ROM software helped them provide better patient care (46.8%) and kept them current on new information and techniques (48.4%). Indications for medical education, libraries and CD-ROM publishers are noted. 相似文献
