- Abstract
- Probably the most interesting, original and controversial indexing system of the 1970s has been PRECIS (the Preserved Context Index System) developed by Derek Austin. It attracted such attention that the short courses given at the British National Bibliography offices in London -initiated as a means of teaching the staff of BNB who did subject indexing-were repeated all over the world, in the form of three-day or three-week sessions. A few fortunate non-BNB indexers were taken into London classes, taught by Austin and Digger, and had the advantage of a week's work with the regular staff theresomething that could not be done elsewhere. In addition, descriptions of the system were published from time to time as progress was made an the system itself and clarification or updating were needed. This article has been selected as an example of clarification. A second edition of the original 1974 Manual describing PRECIS appeared in early 1984, so the system may now be regarded as fully mature. PRECIS, which is the culmination of Austin's research for the Classification Research Group plus considerable additional input from the science of linguistics, is a highly sophisticated indexing system, deliberately created to be used with a computer. The motive behind it was that the indexer should do the brain work and the computer the nitty-gritty work of manipulating index terms. Chosen combinations and permutations are used as head words under strict rules to ensure that the context which defines the specific meaning of these words is always present, thus avoiding the ambiguity problem in indexing. The system also has classifi ation features, in part drawn from the Group's long interest in faceted classification. The actual index produces a large number of index entries, each carrying with it the basic context of the item being described. A weIl-defined terminology, in addition to contextdependency, is a feature of PRECIS. Role operators define the types of terms used and control the manipulations of the terms, which are originally entered as a string. The indexer is able to analyze and reduce to string form any document, process, or material that can be described in words, making it ideal for most audiovisual material.
The system itself has two major aspects: - a syntactic approach in which relationships between terms are identified and tagged. Suitable algorithms for manipulation produce a very thorough index in which each head word is kept in context. - a semantic approach in which terminology is weIl defined by ensuring that the relationships of equivalence, hierarchy, and association are clearly established. Charts of relationships are created by inductive means (i.e., from the ground up). A special code for computer manipulation is used with each line of the string. This translates the string format into one that, with specially derived algorithms, can be used by the computer, to produce the actual index headings with all parts rotated by following the algorithm. The PRECIS system has been translated and utilized for languages other than English, notably French, German, and Danish. Modifications needed for idiosyncracies of each language have been made. Some, such as those modifications needed for German, have turned out to have usefulness with English as weIl. All in all, the system has such advanced indexing concepts that it provides a kind of indexing not possible before the computer came into common usage. Austin, who joined the staff of the British National Bibliography in 1963, is currently a member of the British Library staff. His early work included a NATO-sponsored research assignment for the Classification Research Group (q.v.). This, in turn, led to the development of PRECIS.

- Abstract
- Testing on the syntactic component of the language is in progress, carried out by a team working on the basis of some terms of the Thesaurus which have been identified for possessing some special features. This will maybe lead to some changes and simplifications in the original structures coming from the GRIS model <http://wwwaib.it/aib/commiss/gris/ guida.htm> and the Feasibility Study. Within June 2006, two basic documents will be published: - a paper volume containing the Rules, concerning both terminology and syntax, explanations of the Thesaurus, criteria, choices made about the categories and the width of the semantic network, etc.; - a CD containing the Thesaurus. One side of great interest will be the c-learning process of the indexing language of the new Soggettario. This has to be undertaken only after the prototype stage is done. At that time, once the text of the Rules will have been published, it will be possible for the system to spread, to be learned, and to be tested by various indexers and partners.

- Abstract
- Moving to a fully faceted syntax would resolve three problems facing Library of Congress Subject Headings (LCSH): 1. Inconsistent syntax rules; 2. Inability to create headings that are coextensive with the topic of a work; and 3. Lack of effective displays for long lists of subdivisions under a single subject heading in OPACs and similar electronic displays. The authors advocate a fully faceted syntax using the facets of a modern faceted library classification (The Bliss Bibliographic Classification, 2d ed.). They demonstrate how this might be accomplished so as to integrate the new syntax with existing headings.

- Abstract
- In 1986 Libraries Unlimited published Cochrane's book, Improving LCSH for Use in Online Catalogs; Exercises for Self-Help with a Selection of Background Readings. This was preceded in 1981 by an ERIC publication (ED 208 900) by Cochrane, with Monika Kirtland Bibliographic and Bibliometric Essay which documented critical views of LCSH and an analysis of vocabulary control in LCSH (parts of which were published in Cataloging & Classification Quarterly' 1(2/3) (1982), 71-94). Three features of LCSH will be re-examined to check on progress since the time of these earlier publications: notes, structure of relationships between headings in the list, and links between Library of Congress classification numbers and LCSH or other vocabularies

- Abstract
- PhySH (Physics Subject Headings) was developed by the American Physical Society and first used in 2016 as a faceted hierarchical controlled vocabulary for physics, with some basic terms from related fields. It was developed mainly for the purpose of associating subjects with papers submitted to and published in the Physical Review family of journals. The scheme is organized at the top level with a two-dimensional classification, with one dimension (labeled "disciplines") representing professional divisions within physics, and the other dimension (labeled "facets") providing a conceptual partitioning of terms. PhySH was preceded in use by PACS ("Physics and Astronomy Classification Scheme"), which was in turn preceded by more ad hoc approaches, and this history and related vocabularies or categorizations will also be briefly discussed.

- Abstract
- Pauline Cochrane and Monika Kirtland's "Critical views of LCSH-Library of Congress Subject Headings: a bibliographic and bibliometric essay" published in 'Cataloging & classification quarterly 1(1982) S.71-93' has been widely cited as a source for discussion and complaints about LCSH. Cochrane and Kirtland cover the literature from 1944-1979. The present work provides a critique of the Cochrane/Kirtland study and a survey of the literature concerning the LCSHs during the 1980s. The classified bibliography is arranged according to the format of the Cochrane/Kirtland study to facilitate comparison. Criticism of LCSH reiterates the same points over and over again, whether it is sparseness, bias or currency of the subject headings. Significant trends which emerged in the 1980s include an increased emphasis on the use of LCSH as an online searching tool, concern for the syndetic structure of LCSH and the role of subdivisions, as well as repeated calls for the development of coherent standards to ensure LCSH evolves and is applied in a consistent manner
