- Abstract
- Presentation of Brooke's law for measuring the ageing of scientific literature was first introduced in 1970. Analyses 5 methods of statistical analysis based on this mathematical model: maximum citation, half-life, Griffiths' method, Brookes' graphical analysis and linear regression. Compares results from practical examples using each method, showing Griffiths to be imprecise and unstable, while the others produce similar results. Potential sources of error (size of sample and of age interval) can be readily controlled. An annotated bibliography is appended

- Abstract
- The field of knowledge organization (KO) can be described as composed of the four distinct but connected layers of theory, systems, representation, and application. This paper focuses on the relations between KO theory and KO systems. It is acknowledged how the structure of KO systems is the product of a mixture of ontological, epistemological, and pragmatical factors. However, different systems give different priorities to each factor. A more ontologically-oriented approach, though not offering quick solutions for any particular group of users, will produce systems of wide and long-lasting application as they are based on general, shareable principles. I take the case of the ontological theory of integrative levels, which has been considered as a useful source for general classifications for several decades, and is currently implemented in the Integrative Levels Classification system. The theory produces a sequence of main classes modelling a natural order between phenomena. This order has interesting effects also on other features of the system, like the citation order of concepts within compounds. As it has been shown by facet analytical theory, it is useful that citation order follow a principle of inversion, as compared to the order of the same concepts in the schedules. In the light of integrative levels theory, this principle also acquires an ontological meaning: phenomena of lower level should be cited first, as most often they act as specifications of higher-level ones. This ontological principle should be complemented by consideration of the epistemological treatment of phenomena: in case a lower-level phenomenon is the main theme, it can be promoted to the leading position in the compound subject heading. The integration of these principles is believed to produce optimal results in the ordering of knowledge contents.

- Abstract
- Presents an analysis of the new Spanish edition of the UDC (1995) as compared to the previous abbreviated version (1991). The changes in physical presentation (ligibility), the systematic tables (elaboration, additions, deletions) and the retrieval of information through the use of the index, have all been revised. Evaluates the practicality of the new edition when applied to the classification of actual documents
