- 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
- Account of the experience of the International Maize and Wheat Improvement Centre CIMMYT based in Mexico, which employs some 100 scientists and 600 support staff. To improve services the library updated its system using DB/Textworks, software which can manage large quantities of text including both data and images. The system is structured into modules for cataloguing, circulation, user information, serials, acquisition and suppliers. The chief advantages for medium sized libraries such as CIMMYT is its simplicity; tasks such as defining databases, creating reports, exchanging information so not require the intervention of computer experts

- Abstract
- The increasing emphasis on the importance of corporate intelligence in promoting competitiveness has generated demand for a new interdisciplinary service based on providing data and information geared to the needs of decision makers. The mission of corporate intelligence is to create products such as verbal and audiovisual presentations, bulletins / newsletters, and summary reports, relevant to the immediate specific needs of the organisation. This new service transforms isolated data into high value added information products, opening up new opportunities for interdisciplinary specialists in business information units

- Abstract
- Reports of a study in a Chilean university library, comparing 100 users of online databases and CD-ROMs with 100 users of non-computerized bibliographical resources. Results showed that users tended to be teachers / researchers, and potential users were postgraduate students. Comparison of search results showed online searching improved results and saved time. The chief reasons for non-use were ignorance of the service and use of own personal computer. The study indicated the need to review policy on database acquisition and improve promotion of the service. In general, librarians should motivate greater use of online searching by providing skilled intermediary services to maximize uptake
