Document Delivery for Sci-Tech Libraries touches on important aspects of document delivery and the place each aspect holds in the overall scheme of things. It covers a broad spectrum of topics including traditional techniques, such as interlibrary loan, and more modern ones, such as online ordering. Authors discuss document delivery in relation to their own experiences at the Document Delivery Service, Air Products & Chemicals, Johns Hopkins University's Applied Physics Laboratory, Cutter Laboratories, and the National Bureau of Standards.
