||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.
