    Abstract
    MARC (Machine Readable Cataloguing) format has been widely used and discussed in the library profession. However, there appear to have a wide spread misunderstanding of its real structure and attributes. Discusses the need for use to understand it a little more. Presents the general misconceptions about MARC, the structure of MARC format. In this library automation age, MARC is a key element in library services, and it deserves another look.

    Abstract
    Explains how a computer indexing system works. Reviews fundamentals of how data are stored and retrieved by computers. Describes B-Tree and B+-Tree indexing structures. Gives basic keyword searching techniques that the user must apply to make use of the indexing programs. The demand for keyword retrieval is increasing and librarians should expect to see the keyword-indexing feature become commonly available
