Library managers are becoming increasingly concerned about document delivery systems because the means to identify and locate materials has improved faster than the ability to provide the materials and because a cut‐back in library budgets is forcing libraries to borrow or obtain more material from other sources. A new SPEC kit (no. 82, March 1982) has been produced on document delivery systems in use in the Association of Research Libraries. The September 1981 survey covered two categories of service: internal delivery — disseminating locally‐owned materials to users, and external delivery — acquiring materials from an outside source for local users. Some ninety ARL libraries responded to the survey by providing materials and information describing the methods they employ. These include telefax, requests via electronic mail and OCLC's interlibrary loan subsystem and online ordering from data‐bases. SPEC kit #82 contains twenty‐six documents, (101 pages) and is available for $15 (prepaid) from Systems and Procedures Exchange Center, OMS/ARL, 1527 New Hampshire Ave., NW, Washington DC 20036, USA.
