contents	Microfiche/Telex Oriented Document Services Center Established in Sylvania Library Through Cooperative Test Program with Defense Documentation Center. Little, Dean K. Communications Information Centers Information Dissemination Information Retrieval Information Services Microfiche Use Studies In a cooperative program with Defense Documentation Center Headquarters, Sylvania arranged for procurement of 70,000 unclassified-unlimited documents without DDC Form I cards and 30,000 unclassified-limited and classified documents with Form I's. This was done in order to overcome effects of an in-house documents inventory/selective destruction program and the DDC decision to close their Regional Field Service Offices which increased access time to contract documentation in the DDC Regional Office locales from minutes to over two weeks. Western Union TELEX with tape transmission was installed for transmitting Rapid Response Bibliography (RRB) search requests to DDC for overnight computer searches. The TELEX system in conjunction with the in-house collection of microfiche documents and microfiche duplicating equipment, provided the library with quick reaction capability in (1) literature identification, (2) full text acquisition, and (3) copy reproduction of no-return copies of master file microfiche. Statistics kept on the use of the system indicated that while users preferred hard copy, they were willing to use microfiche because of its quick accessibility. (Author/CC)
