- Abstract
- The technical and administrative problems involved in the storage, handling, and retrieval of library information are emphasized throughout this detailed account of the present equipment used. Reference is made to previous studies and suggestions given for future research. Particular attention is paid to the need for fundamental systems studies and for full investigation of the requirements of the scholar. The author concludes that the problem was proceeded in a piecemeal and 'gadget' fashion and stresses the need for more detailed analysis of the usefulness and economic justification of each separate piece of machinery, without, however, losing sight of the problem in its entirely. By way of practical illustration a method for making the recources of Harvard University's Lamont Library available to all colleges is suggested at the end.

- Abstract
- A classification is a theory of the structure of knowledge. From a discussion of the nature of truth, it is held that scientific knowledge is the only knowledge which can be regarded as true. The method of induction from empirical data is therefore applied to the construction of a classification. Items of knowledge are divided into uniquely definable terms, called isolates, and the relations between them, called operators. It is shown that only four basic operators exist, expressing appurtenance, equivalence, reaction and causation; using symbols for these operators, all subjects can be analysed in a linear form called an analet. With the addition of the permissible permutations of such analets, formed according to simple rules, alphabetical arrangement of the first terms provide a complete, logical subject index. Examples are given, and possible difficulties are considered. A classification can then be constructed by selection of deductive relations, arranged in hierarchical form. The nature of possible classifications is discussed. It is claimed that such an inductively constructed classification is the only true representation of the structure of knowledge, and that these principles provide a simple technique for accurately and fully indexing and classifying any given set of data, with complete flexibility

- Abstract
- The growth of the rules which shape library catalogs and determine their character and usefulness is susceptible of much more extended treatment than is possible here. What is attempted in the following pages is to point out present trends and to indicate their significance. Evidently the year 1941 marked the beginning of a new phase in the evolution of cataloging rules. The publication then of the preliminary American second edition of the A.L.A. Catalog Rules appears as the culmination of a movement inspired exactly one hundred years earlier by the issue of Panizzi's rules. The latter followed a very long period in which rudimentary methods of cataloging slowly evolved and the need of rules to systematize the work gradually came to be recognized. As long as libraries were small and few books were published, the contents of a library could be recorded in any fashion that struck the fancy of the one in charge. Catalogs were made by librarians largely for their own use and had one simple function, that of an inventory or a collection of lists showing the holdings. The form and arrangement of the entries were arbitrary.

- Abstract
- In distinction to current Theory of Communication which treats amount of information as a measure of the statistical rarity of a message, a Theory of Semantic Information is outlined, in which the concept of information carried by a sentence within a given language system is treated as synonymous with the content of this sentence, normalized in a certain way, and the concept of amount of semantic information is explicated by various measures of this content, all based on logical probability functions ranging over the contents. Absolute and relative measures are distinguished, so are D-functions suitable for contexts where deductive reasoning alone is relevant and I-functions suitable for contexts where inductive reasoning is adequate. Of the two major types of amount of information investigated, the one, cont, is additive with respect to sentences whose contents are exclusive, the other, inf, with respect to sentences which are inductively independent. The latter turns out to be formally analogous to the customary information measure function. Various estimate functions of amount of information are investigated leading to generalized semantic correlates of concepts and theorems of current Communication Theory. A concept of semantic noise is tentatively defined, so are efficiency and redundancy of the conceptual framework of a language system. It is suggested that semantic information is a concept more readily applicable to psychological and other investigations than its communicational counterpart.
