The second of four volumes in a series describing the basic documentation practices involved in the initial setting up and subsequent operation of an information-library organization to provide defense-aerospace scientific and technical information services, this manual consists of three sections. "Data Recording and Storage," by J. Howard Petrie, provides an introduction to the hardware and software of computer systems, discusses the problems of inputting data, describes different types of input and storage equipment, and outlines management and systems analysis problems in the project environment. "Mechanization Systems and Operations," by Victor Rogers, provides a working basis for setting up a computer system for indexing, processing, and disseminating information, mainly in the form of bibliographic references. The main emphasis is on the in-house computer and methods are described for setting up, storing, and exploiting databases, and creating an announcement journal. "Announcement Services and Publications," by Elizabeth Ridler, reviews methods for announcing holdings and new acquisitions to users, provides examples of manually and computer produced bulletins, and discusses the production of indexes to computer produced publications. Also described are manual and computer-based SDI services and repackaging of literature resources as bibliographies, state of the art reports, and packaged information for technical innovation.
