- Abstract
- Aus der Benutzung der Universitätsbibliothek Ulm wurde eine Halbwertszeit-Funktion in der naturwissenschaftlichen Literatur von t1/2=5 Jahren bestimmt. Eine interessante Abweichung von dieser Halbwertszeit-Funktion ist bei der Bestellung der neuesten Zeitschriften zu beobachten. Der Grund hierfür liegt vermutlich darin, daß Wissenschaftler das Vierfache an neuester Literatur lesen müssen, um wissenschaftliche Trends zu überschauen. Eine weitere Abweichung ist in der ältesten Literatur festzustellen, bei den sog. 'citation classics'. Übereinstimmung zeigt sich im Zitier- und Kopierverhalten bei Zeitschriftenliteratur, die älter als 2 Jahre ist. Etwa 27% der an die UB Ulm gerichteten Literaturanforderungen betreffen Zeitschriftenaufsätze mit einem Alter von über 10 Jahren, da diese Bestände für die Benutzer nur schwer zugänglich sind. Dies zeigt die große Bedeutung einer Freihand-Bibliothek

- Abstract
- Thesauri have been used in the library and information science field to provide a standard descriptor language for indexers or searchers to use in an informations storage and retrieval system. One difficulty has been the maintenance and updating of thesauri since terms used to describe concepts change over time and vary between users. This study investigates a mechanism by which thesauri can be updated and maintained using citation, co-citation analysis and citation context analysis.

- Abstract
- Scientific documents are more or less important in relation to give subjects and this importance can be measured. An empirical investigation into philosophical information was carried out using a weighting algorithm developed by N. Henrichs which results in a distribution by weighting of documents on an average philosophical subject. With the aid of statistical methods a threshold value can be obtained that separates the important and unimportant documents on a subject. The knowledge of theis threshold value is important for various practical and theoretic questions: providing new possibilities for research strategy in information retrieval; evaluation of the 'titleworthiness' of subjects by comparison of document titles and themes for which the document at hand is important; and making available data on thematic trends for scientific results

- Abstract
- In a bibliometric study of references to indexing and abstracting from 1876 to 1976 a total of 2.381 references in Wellisch's Indexing and abstracting: an international bibliography were analysed by a PL/I program. Most of the articles (67%) appeared as journal papers. The Bradford-Zipf law was applied to investigate the journal literature. Thirteen core journals were identified, six of which emphasize the subject of indexing and abstracting. Lotka's law was used to measure the productivity of authors. The vast majority, 1.533 out of 1.966 authors, contributed only one article. The leading authors and their active life in this subject were also studied. English is the predominant language of articles on indexing and abstracting

- Abstract
- Q-analysis is a methodology for investigating a wide range of structural phenomena. Strutures are defined in terms of relations between members of sets and their salient features are revealed using techniques of algebraic topology. However, the basic method can be mastered by non-mathematicians. Q-analysis has been applied to problems as diverse as discovering the rules for the diagnosis of a rare disease and the study of tactics in a football match. Other applications include some of interest to librarians and information scientists. In bibliometrics, Q-analysis has proved capable of emulating techniques such as bibliographic coupling, co-citation analysis and co-word analysis. It has also been used to produce a classification scheme for television programmes based on different principles from most bibliographic classifications. This paper introduces the basic ideas of Q-analysis. Applications relevant to librarianship and information science are reviewed and present limitations of the approach described. New theoretical advances including some in other fields such as planning and design theory and artificial intelligence may lead to a still more powerful method of investigating structure
