Conversion of infrequently used material to microform permits the addition of new titles not otherwise affordable. The Sociology Dept. is commendably responsive to increasing the collection in this way. Large microform sets such as the recent Gallup Poll of Canada are occasionally purchased. 2.6.4 Reference Materials Reference works are a cornerstone of the collection. Standard dictionaries, encyclopedias and directories are added comprehensively.
Indexes are vital in unlocking the contents of the journal literature.
Bibliographies are emphasized to provide access to material not held by the library. The powerful and sophisticated features of CD-ROM make them very appealing. Because of the high cost, new requests are carefully scrutinized. Cancellation of the print counterpart is frequently necessary to afford the CD version. The implications of CD-ROM in increasing demand for additional journals should also be considered.
