Abstract

Gives an account of the theoretical work underpinning the development of subject heading schemes for Italian libraries, as developed by the GRIS collaborative project of Italian research and academic libraries. Discusses semantic categories and principles of citation, rules for the syntax of subject headings, and logica syntactic principles for citation order

Abstract

Continuing a previous article on CDS/ISIS Micro functions and procedures, illustrates other aspects by recapitulating the strong and weak points of the system. Defects include lack of user firendliness, the search and cataloguing functions, index management, and import/export. Favourable features are total file definition, the formatting language, alphabetical sorting, commands, and data transfer to/from other software environments. ISIS, developed by UNESCO, is a good product, and although demanding for the user, repays the effort made

Abstract

The Bünau Library catalogue (1750-56), which initially comprised 3 tomes of 7 volumes and had 16.000 authors listed in its final index, is the most systematically structured in the history of bibliography, its architecture being so analytical that it almost fulfils the librarian's dream of so organising a collection that it develops organically from within. Describes with examples of indexing the work of the Bünau Library's first director, J.M. Franke (1717-75), who began his task with the 42.000 volumes in Count Heinrich von Bülau's private collection, and later supervised their incorporation with the Brühl and Dresden Electoral Library collections

Footnote

An entry is structured so as to present all the essential elements of the indexing system. For each term are given: category, facet, related terms, Dewey interdisciplinary class number and, if necessary; definition or scope notes. Sources used are referenced (an appendix in the book lists those used in the current work). Historical notes indicate whenever a change of term has occurred, thus smoothing the transition from the old lists. In chapter 5, the longest one, detailed instructions with practical examples show how to create entries and how to relate terms; upper relationships must always be complete, right up to the top term, whereas hierarchies of related terms not yet fully developed may remain unfinished. Subject string construction consists in a double operation: analysis and synthesis. The former is the analysis of logical functions performed by single concepts in the definition of the subject (e.g., transitive actions, object, agent, etc.) or in syntactic relationships (transitive relationships and belonging relationship), so that each term for those concepts is assigned its role (e.g., key concept, transitive element, agent, instrument, etc.) in the subject string, where the core is distinct from the complementary roles (e.g., place, time, form, etc.). Synthesis is based on a scheme of nuclear and complementary roles, and citation order follows agreed-upon principles of one-to-one relationships and logical dependence. There is no standard citation order based on facets, in a categorial logic, but a flexible one, although thorough. For example, it is possible for a time term (subdivision) to precede an action term, when the former is related to the latter as the object of action: "Arazzi - Sec. 16.-17. - Restauro" [Tapestry - 16th-17th century - Restoration] (p. 126). So, even with more complex subjects, it is possible to produce perfectly readable strings covering the whole of the subject matter without splitting it into two incomplete and complementary headings. To this end, some unusual connectives are adopted, giving the strings a more discursive style.
