Reference activity and the external user: confluence of community needs at a medical school branch library.

The allocation of reference services between primary and secondary users constantly challenges academic medical libraries. Routine statistics at a medical school branch library suggested that over 40% of its reference transactions involved persons not affiliated with the university. To investigate this finding, a survey of reference activity was conducted using measurement techniques unobtrusive to the user. Fifteen data items were recorded, including user status, type of question, intended use of information requested, status of staff taking request, and staff time spent. Survey results showed that nonaffiliates accounted for 51% of reference activity. Based on this documented data, definitive reference guidelines addressing hours, priority of requests, charges, and staffing patterns can now be developed. Findings will also assist in evaluating the library's regional role, in formulating marketing strategies, and in determining library objectives.
