All United States academic members of the Association of Research Libraries (ARL) were surveyed to determine (1) how many hours a week librarians were expected to devote to their primary assignment, (2) how many months a year they worked compared to most other faculty members on their campus, (3) whether research and scholarship were requirements for promotion and tenure, and (4) whether the library granted its professionals released time for research. Eighty percent of those questioned responded; fifty-one percent (35) of the libraries offer faculty status for librarians. Although most libraries incorporate evidence of research into their promotion and tenure requirements, very few make released time available on a regular basis. An examination of the promotion and tenure documents of these libraries revealed that, although criteria used to evaluate librarians resemble those used for their teaching colleagues, their work week requirements and the length of their yearly contracts differ significantly. A summary of the rsponses to the questionnaire used in the study is included with the report. (Author/JD)
