This study examines the interlibrary loan requests made to NEOUCOM's (Northeastern Ohio Universities College of Medicine) Oliver Ocasek Regional Medical Information Center in Rootstown, OH from its associated council hospital libraries. A total of 636 interlibrary loan requests from the period July 1994-July 1995 were analyzed. Components of the interlibrary loan form assessed were the requesting hospital; the type, year, and subject of the material requested; time it took to fill the request; if the request was filled on or before the day it was needed; and the type of patron requesting the material. Interlibrary loan requests from the hospital libraries to the Information Center were filled in a short amount of time, and all of the requests analyzed were filled on or before the day they were needed, except one. Three hospitals had the most interlibrary loan requests. Overall characteristics of the most requested type of item were: generally an article from a journal, dated from 1980-1995, and dealing with preclinical sciences. Of the patrons identifying themselves on the interlibrary loan form, 40% were doctors. A profile of each hospital compiled from the study findings is provided. Appendices include a list of Council of Associated Hospital libraries; sample interlibrary loan form; coding sheet; and National Library of Medicine classification sheet. (Contains 20 references.)
