Abstract The purpose of the Air Pollution Technical Information Center (APTIC) was to provide bibliographic control of the world's technical literature relating to air pollution, in accordance with a delegation from the Office of Science and Technology in January 1964. APTIC screened: 7,000 periodicals; government reports; patents; technical papers; preprints; dissertations; translations; proceedings; etc. Relevant information was selected, abstracted, indexed, and recorded on computer magnetic tape. This tape records free language index terms (not covered by the controlled index terms in the APTIC bibliogrphic file), and the document number(s) to which each term refers. EPA makes the file accessible on an international on-line retrieval network (currently, under terms of an EPA contract, on the Lockheed system.)
Availability Notes Source tape is in ASCII character set. Character set restricts preparation to 9 track one-half inch tape only. Identify recording mode by specifying density only. Call NTIS Computer Products, if you have questions.
