The bibliography consolidates into one publication all reports previously published in the EPA Publications Bibliography, Quarterly Abstract Bulletin from 1984 through 1990. It is published in two parts. Part 1 contains bibliographic citations with abstracts. Part 2 contains seven indexes: Title, Keyword, Sponsoring EPA Office, Corporate Author, Personal Author, Contract/Grant Number and NTIS Order/Report Number. Two cumulated bibliographies of EPA reports precede the publication. EPA Publications Bibliography, 1970-1976 (order number PB-265920) contains reports generated by EPA and its predecessor agencies. The EPA Publications Bibliography, Quarterly Abstract Bulletin, is published by NTIS as a current awareness subscription service. Bibliographic records of all EPA reports in the NTIS collection are contained in the NTIS Bibliographic Database and are searchable online through various commercial vendors. Copies of individual reports are available in paper or microfiche form. Prices for reports listed with NTIS price codes may be determined by consulting the price code list published in the most recent EPA Publications Bibliography, Quarterly Abstract Bulletin or by requesting a current schedule from NTIS.
