ANNOUNCEMENT OF NASA PUBLICATIONS IN STAR
Scientific and technical reports produced by NASA and its contractors and grantees, or in conjunction with other Government agencies, and other selected documents released by NASA are identified by an asterisk (*) following the accession numbers (e.g.. N7210748*). Prior to their announcement in STAR, these NASA publications are assigned a specific NASA report number, which is shown on the last line of the STAR citation. The nature of NASA publications is specified by the report number series, identified by a prefix to the report number: TR-R. TN-D. TM-X. TT-F. CR. or SP. These series refer respectively to NASA Technical Reports, which contain significant and complete contributions to scientific and technical knowledge; Technical Notes, reports of similar quality but lesser scope: Technical Memorandums, reports containing preliminary data or of specialized utility: Technical Translations, information published in a foreign language and considered to merit NASA distribution in English: Contractor Reports. information generated under NASA-sponsored contracts, grants, or interagency agreements; and Special Publications, which include conference proceedings. monographs, data compilations, sourcebooks, special bibliographies, and other publications derived from or of value to NASA activities. Reports in these series that are printed by NASA are often referred to as "low'numbered" or "low series" publications, because the report number is always below 50.000 (8.000 for Technical Translations). Some TM-X and CR reports are numbered above 50.000, are referred to as "high-numbered" or "high series" publications, and are generally available only in microfiche or facsimile reproductions.
DISTRIBUTION OF NASA PUBLICATIONS
NASA distributes its publications to qualified recipients who have registered as described in the next paragraph. (Public availability of NASA reports and other publications announced in STAR is discussed separately in this Introduction.) Automatic distribution of low series NASA reports can be made in either paper (printed) copy or microfiche. High series NASA reports are given automatic distribution only as microfiche. The automatic distribution of a NASA report, in paper copy and/or microfiche, is made under the same subject category in which it is announced in STAR. A printed low series report usually is disseminated four to six weeks prior to its announcement in STAR. Microfiche of both low and high series reports are disseminated concurrently with STAR announcement. Automatic distribution of NASA documents is supplemented by a secondary request service, usually for microfiche copy only. which NASA may provide to qualified registrants.
ELIGIBILITY AND REGISTRATION FOR NASA INFORMATION PRODUCTS AND SERVICES
A variety of services, in addition to the distribution of NASA scientific and technical reports and of STAR and its cumulative indexes, is available to organizations of the following type that have registered with NASA to receive specific services or products:
1. NASA offices, research centers. contractors, subcontractors, grantees, and con
sultants: 2. Other U.S. Government agencies and their contractors; 3. Libraries in the United States that have arrangements with NASA to maintain
(1) A microfiche is a transparent sheet of film, 105 by 148 mm in size, containing
collections of NASA documents for public reference; 4. Other organizations in the United States having a need for NASA documents in
work related to aeronautics and space research; 5. Organizations abroad that have established reciprocal document exchange arrange
monts with NASA. Only the contral service points or central points of document acquisition and control within qualified organizations are eligible to register for NASA products and services. Domestic organizations that may be eligible to receive various classes of NASA publications and services should address their requests for registration or for further information to:
