    Abstract
    This paper presents a mathematical model of an information retrieval system thought to be general enough to serve as an abstract representation of most document and reference retrieval systems. The model is made up of four components that, in one form or another, appear in every functioning system. It is proved that the basic organization of documents that the system provides for a user on receipt of a request follows from the properties and interrelations of the four components. Each component is then discussed in turn and it is seen that much of the existing theory regarding information systems can be viewed as an elaboration of this model

    Abstract
    The indexing of a document is among the most crucial steps in preparing that document for retrieval. The adequacy of the indexing determines the ability of the system to respond to patron requests. This paper discusses this process, and document retrieval in general, on the basis of formal decision theory. The basic theoretical approach taken is illustrated by means of a model of word occurrences in documents in the context of a model information system; both models are fully defined in this paper. Through the main purpose of this papers is to provide insights into a very complex process, formulae are developed that may prove to be of value for an automated operating system. The paper concludes with an interpretation of recall and precision curves as seen from the point of view of decision theory

    Abstract
    One of the most surprising findings in the information sciences is the recurrence of a small number of frequency distributions. In this paper, these distributions are described, and a point of view is adopted that allows us to understand them a being different versions of a single distribution. The empirical distributions are shown to be special cases of a single theoretic distribution. It is found that when random fluctuations are introduced, the distributions are not strongly influenced
