    Abstract
    An essential part of information retrieval knowledge is the knowledge of data base contents and structures. Currently, the variety of data bases is so wide that it is difficult to know the contents and structure of a particular data base and how they differ from those of other data bases. Because of the lack of commonly acknowledged guidelines for data base descriptions, each on-line service designs and produces printed manuals, on-line help texts and other user documentation in its own manner. For the presentation of exact information and knowledge on a data base, common, structured principles for data base descriptions are needed. Requirements and some solutions for such description principles are presented.

    Abstract
    A study was done to test the effectiveness of retrieval using title word searching. It was based on actual search profiles used in the Mechanized Information Center at Ohio State University, in order ro replicate as closely as possible actual searching conditions. Fewer than 50% of the relevant titles were retrieved by keywords in titles. The low rate of retrieval can be attributes to three sources: titles themselves, user and information specialist ignorance of the subject vocabulary in use, and to general language problems. Across fields it was found that the social sciences had the best retrieval rate, with science having the next best, and arts and humanities the lowest. Ways to enhance and supplement keyword in title searching on the computer and in printed indexes are discussed.
