    Abstract
    Introductory reading list covering most of the areas of modern classification theory. Includes definitions, bibliographic and nonbibliographic classification, recent views on classification, subjects related to classification, and miscellaneous background material such as scientific method, logic, statistical methods, etc.

    Abstract
    This paper is concerned with recent work in the theory of information retrieval. More particularly, it is concerned with theories which tackle the problem of retrieval performance, in a sense which will be explained. The aim is not an exhaustive survey of such work; rather it is an analysis and synthesis of those contributions which I feel to be important or find interesting
