The prompt return of checked out materials has been demanded by libraries for more than a century. Together with other measures such as overdue fines, library notices are used to bring in prompt returns by informing the users of their checked out items that will soon be due or are already overdue. The analysis of library notices sent in the past five years indicates courtesy notices that alert users of their soon-to-be-due items fail to improve prompt return significantly. On the other hand, sustaining the library notice service takes effort and cost. In this age of technology, prompt return may perhaps be viewed in a new perspective that serves the users and the library better. (Contains 1 table.)
