This study reports findings from a survey of U.S. and Canadian medical libraries belonging to the Association of Academic Health Sciences Library Directors (AAHSLD). Conducted in the spring of 1990 and funded by AAHSLD, the survey had the two primary purposes of assessing the use of the AAHSLD "Annual Statistics" in providing data for decision making, and offering recommendations to improve the usefulness of the "Annual Statistics." Usable responses were received from 83 of the 144 medical libraries surveyed. Both quantitative and qualitative assessments were made on the survey data, and the findings generally suggest satisfaction with the "Annual Statistics." However, the "Annual Statistics" could be improved by including more performance measures and categorizing some of the data differently. Other findings and specific recommendations to improve the publication are included in the report. A copy of the questionnaire and comments on individual questions by the respondents are appended.
