- Abstract
- A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

- Abstract
- This paper reports the results of a year-long survey conducted at the University of Pittsburgh (Pitt) to determine what level of cataloging copy (Library of Congress, member input, or none) is present on OCLC at the time an item is received in Technical Services and after a six-month waiting period. These results were used to divert selected monographs from the normal workflow in order to expedite their cataloging and to release needed shelf space for other items.

- Abstract
- The development of excellent reference skills is an art, and requires skill. Knowledge of how reference works are organised and work is of utmost importance. The librarian is also required to appreciate and understand user needs. It is necesary to solicit the real uestion, which often is not the one asked.

- Abstract
- A study was done to test the effectiveness of retrieval using title word searching. It was based on actual search profiles used in the Mechanized Information Center at Ohio State University, in order ro replicate as closely as possible actual searching conditions. Fewer than 50% of the relevant titles were retrieved by keywords in titles. The low rate of retrieval can be attributes to three sources: titles themselves, user and information specialist ignorance of the subject vocabulary in use, and to general language problems. Across fields it was found that the social sciences had the best retrieval rate, with science having the next best, and arts and humanities the lowest. Ways to enhance and supplement keyword in title searching on the computer and in printed indexes are discussed.

- Abstract
- Reference librarians, who are thoroughly familiar with the purpose, scope and arrangement of abstract periodicals, are uniquely qualified for the task of writing abstracts. The procedures described here offer a relatively simple way for them to write acceptable abstracts from the outset. Although research is being conducted in the area of machine generated abstracts, there wll continue to be a role for human abstractors.

- Abstract
- The university libraries at Virginia Polytechnic Institute and State University began an innovative indexing method in 1985 with the objectives of stronger and easier subject access to local newspapers and the creation of an index which could store information compactly and economically. Discusses the decision to use Pro-Cite software and describes the creation of 10 area data base files. Outlines 2 areas of difficulty: documentation and terminology.

- Abstract
- The Anglo-American Cataloguing Rules, second edition, aim at universal applicability. Some problems brought forth through the translation process and the laws in the workability of rules in a nonEnglish working language are examined. This leads to acknowledge the failure of AACR2 to acquire an international adaptability. Enquiry into the needs of potential users is advised.

- Abstract
- Traditional cataloging support services such as typing and filing are gradually being eliminated in favor of more sophisticated skills. Library staff members who are specialized in imminently obsolete skills must be re-educated to become productive participants in the "Golden Age" of technology. The Catalog Management section at the Iowa State University Library is attempting to make this process painless and exciting for all of its employees.

- Abstract
- The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

- Abstract
- Paper presented at a symposium on 'Implementing the Art and Architecture Thesaurus (AAT): Controlled Vocabulary in the Extended MARC format', held at the 1989 Annual Conference of the Art Libraries Society of North America. The only way to get bibliographic records on to campus on-line library catalogues, and slide records on the national bibliographic utilities, is through the use of MARC. Discusses the importance of having individual slide and photograph records on the national bibliographic utilities, and considers the obstacles which currently make this difficult. Discusses mapping to MARC from data base management systems.

- Abstract
- The patterns of overlap between terms which are closely related in a thesaurus are considered. The relationships considered are parent/child, in which one term is a broader term of the other, and sibling in which to 2 terms share the same broader term. The patterns of overlap observed in the MeSH thesaurus with respect to selected MEDLINE postings are examined. The implications of the overlap patterns are discussed, in particular, the impact of the overlap patterns on the potential effectiveness of a proposed algorithm for handling negation is considered.

- Abstract
- The development of the general theory of subject indexing language and of POPSI for organisation, storage and retrieval of subjects embodies in documents has a striking parallel in the search for and development of 'universal forms' and 'deep structure' in language and linguistic studies. This paper briefly traces the development of POPSI language as a metalanguage for information organisation and for generating information retrieval thesaurus. Also a computer-based system for generating an information retrieval thesaurus from modulated subject headings formulated according to POPSI which are enriched with certain codes for relating the terms in the subject headings is described. It is also mentioned that, if it is possible to form a table of equivalent terms in another language for the terms already used to generate the thesaurus, then it is possible to translate the thesaurus automatically into the other language

- Abstract
- In subject cataloging of audiovisual materials generic terms like 'documentary' or 'absolute film' facilitate the work of users and librarians. On the concrete level the study shows 4 ways to make a list of generic terms for the application in general libraries. The heuristic function of the study is to offer methods towards the solution of problems in the field of subject cataloguing of non-book materials. (1) The formal subject heading in library science corresponds to generic terms; Anglo-American and German rules for subject cataloging, however, provide no list that is directly applicable. (2) The terminology of institutions administering many audiovisual documents has been examined; general libraries have to find a common denominator with medium depth of classification and balanced representation of fiction and nonfiction terms. (3) From encyclopedic definitions of generic terms 8 dimensions have been extracted characterizing the terms in question individually. (4) The contribution of communication science has been discussed explaining a research project
