Intended to assist academic librarians and other information professionals in better exploiting the information resources available through the National Technical Information Service (NTIS), this two-part manual offers practical suggestions and strategies for making NTIS information services and products available through academic libraries. Suggestions to increase academic librarians' awareness of and access to NTIS services and products are offered in the first section of the manual, including development of a knowledge base of NTIS services and products; taking into account the basic considerations of access, bibliographic control, and microfiche use; development of collections of NTIS materials; promotion of NTIS materials within and outside the library; development of an NTIS service plan; and increasing the use of NTIS materials. This portion of the text is supplemented with 6 figures, and 21 references are provided. The second part of the manual, which identifies core collections of NTIS reports, reference materials, microfiche, diskettes, and magnetic tapes within 16 major subject areas, is intended to help librarians in any setting determine which NTIS titles are significant for particular subject areas and to allow librarians to better integrate NTIS materials into their collections. Indexes by NTIS document title and by order number are included. Instructions for searching OCLC for NTIS materials and an NTIS order form are appended. (KM)
