This handbook is designed primarily as a general orientation aid, not an operation manual. It presents the background (mainly regulatory) of Federal procurement work, details, devices and tactics found to be successful, and calls attention to special sources of supply. Although planned as an aid for librarians who are engaged in Federal procurement work, the handbook will also be useful to nonlibrarian officials who participate in library procurement. The term library materials covers reading matter in all forms and formats as well as audio discs and tapes, computer tapes, and photos. Covered in the section on procurement by purchase are: the relationship between the librarian, procurement officer and finance officer; legal aspects; the nature of the commodity; kinds of libraries; purchase by negotiation; purchase by formal contract; Federal Supply Schedules; publisher plans; government documents; microforms; and patents. The section on non-purchase procurement includes: gifts, exchanges, government documents, depository procurement, and withdrawal of materials. A performance resume is included which identifies and arranges in order the actions generally required of librarians engaged in the procurement process. (Author/JB)
