- Abstract
- Online displays of bibliographic records in call number order can serve various functions. A literature search showed no papers or books discussing this topic directly. Various displays from online catalogues available via the Internet were examined, as were displays sent to the author by colleagues. A number of the displays were uninformative to the extent that the identification of works associated with call numbers was difficult or impossible without follow-up searching of the individual bibliographic records. Other displays provided information where further searching of the database would not be required for most purposes. Displays noted ranged from displays with call numbers alone, with no bibliographic information, to records including main entry, title, statement of responsibility, place, publisher, and date. Suggestions of useful data elements to be included in displays of bibliographic records in call number order are made for the following functions: shelflisting, cataloguing, catalogue maintenance, reference, public searches, acquisition and collection development, and inventory control. Recommendations are made that the following data elements should be present in call number displays: entire call number as a sequencing element; main entry; entire title proper, and the date. Concern is expressed that the call number filing arrangement be that followed in traditional shelflists, and a suggestion is made that possible consensus on the placement of the data elements within a display be considered in the future

- Abstract
- Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

- Abstract
- In addition to using title keywords and subject headings for searching in the online catalog, the searcher may also use class numbers as access points. Library of Congress class or call numbers are particular effective in certain kinds of specific-item subject searching and serve as supplements to keywords and descriptors, improving precision and recall. Class number searching in the database can produce unique results because these numbers collect citations in ways that differ from those of keywords and descriptors

- Abstract
- But what happens to this awareness in a digital library? Can discursive formations be represented in cyberspace, perhaps through diagrams in a visualization interface? And would such a schema be helpful to a digital library user? To approach this question, it is worth taking a moment to reconsider what Radford is looking at. First, he looks at titles to see how the books cluster. To illustrate, I scanned one hundred books on the shelves of a college library under subclass HT 101-395, defined by the LCC subclass caption as Urban groups. The City. Urban sociology. Of the first 100 titles in this sequence, fifty included the word "urban" or variants (e.g. "urbanization"). Another thirty-five used the word "city" or variants. These keywords appear to mark their titles as the heart of this discursive formation. The scattering of titles not using "urban" or "city" used related terms such as "town," "community," or in one case "skyscrapers." So we immediately see some empirical correlation between keywords and classification. But we also see a problem with the commonly used search technique of title-keyword. A student interested in urban studies will want to know about this entire subclass, and may wish to browse every title available therein. A title-keyword search on "urban" will retrieve only half of the titles, while a search on "city" will retrieve just over a third. There will be no overlap, since no titles in this sample contain both words. The only place where both words appear in a common string is in the LCC subclass caption, but captions are not typically indexed in library Online Public Access Catalogs (OPACs). In a traditional library, this problem is mitigated when the student goes to the shelf looking for any one of the books and suddenly discovers a much wider selection than the keyword search had led him to expect. But in a digital library, the issue of non-retrieval can be more problematic, as studies have indicated. Micco and Popp reported that, in a study funded partly by the U.S. Department of Education, 65 of 73 unskilled users searching for material on U.S./Soviet foreign relations found some material but never realized they had missed a large percentage of what was in the database.

- Abstract
- Ia McIlwaine, head of the Classification Research Group and editor of the UDC, noticed that the session's title invited crystal ball gazing, a talent she denied possessing. However, she admitted that she had asked the Classification Research Group to engage in such an exercise with her. The Group found, like the participants at the Allerton Institute were finding, that the contemplation of classification's future provided more questions than answers, but the questions were well worth considering. Her talk focused around a problem which originates in the difference between classifiers' uses and users' uses for classification systems. For users, who speak with the paraphrased self-confidence of Humpty Dumpty, a subject is a subject because they say it is. McIlwaine pointed out that this process of "saying" is at the heart of the users' needs which should be addressed by classification systems. Users use words to approach information systems and their associated classification systems. Classifiers need to recognize that this is the use to which their systems will be put. A body of users external to the classification process will make very different demands upon the system as compared to the users of the classification system who are also the creators of the system. Users desire information grouped for individual usefulness, and the groupings need to be according to words through which users can approach the system.

- Abstract
- In the present work we discuss opportunities, problems, tools and techniques encountered when interconnecting discipline-specific subject classifications, primarily organized as search devices in bibliographic databases, with general classifications originally devised for book shelving in public libraries. We first state the fundamental distinction between topical (or subject) classifications and object classifications. Then we trace the structural limitations that have constrained subject classifications since their library origins, and the devices that were used to overcome the gap with genuine knowledge representation. After recalling some general notions on structure, dynamics and interferences of subject classifications and of the objects they refer to, we sketch a synthetic overview on discipline-specific classifications in Mathematics, Computing and Physics, on one hand, and on general classifications on the other. In this setting we present The Scientific Classifications Page, which collects groups of Web pages produced by a pool of software tools for developing hypertextual presentations of single or paired subject classifications from sequential source files, as well as facilities for gathering information from KWIC lists of classification descriptions. Further we propose a concept-oriented methodology for interconnecting subject classifications, with the concrete support of a relational analysis of the whole Mathematics Subject Classification through its evolution since 1959. Finally, we recall a very basic method for interconnection provided by coreference in bibliographic records among index elements from different systems, and point out the advantages of establishing the conditions of a more widespread application of such a method. A part of these contents was presented under the title Mathematics Subject Classification and related Classifications in the Digital World at the Eighth International Conference Crimea 2001, "Libraries and Associations in the Transient World: New Technologies and New Forms of Cooperation", Sudak, Ukraine, June 9-17, 2001, in a special session on electronic libraries, electronic publishing and electronic information in science chaired by Bernd Wegner, Editor-in-Chief of Zentralblatt MATH.

- SELVI (Knowledge Classification of Digital Information Materials with Special Reference to Clustering Technique) finds that it is essential to classify digital material since the amount of material that is becoming available is growing. Selvi suggests using automated classification to "group together those digital information materials or documents that are "most similar" (p. 65). This can be attained by using Cluster analysis methods. PRADHAN and THULASI (A Study of the Use of Classification and Indexing Systems by Web Resource Directories) compare and contrast the classificatory structures of Google, Yahoo, and Looksmart's directories and compare the directories to Dewey Decimal Classification, Library of Congress Classification and Colon Classification's classificatory structures. They find differentes between the directories' and the bibliographic classification systems' classificatory structures and principles. These differentes stem from the fact that bibliographic classification systems are used to "classify academic resources for the research community" (p. 83) and directories "aim to categorize a wider breath of information groups, entertainment, recreation, govt. information, commercial information" (p. 83). NEELAMEGHAN (Hierarchy, Hierarchical Relation and Hierarchical Arrangement) reviews the concept of hierarchy and the formation of hierarchical structures across a variety of domains. NEELAMEGHAN and PRADAD (Digitized Schemes for Subject Classification and Thesauri: Complementary Roles) demonstrate how thesaural relationships (NT, BT, and RT) can be applied to a classification scheme, the Colon Classification in this Gase. NEELAMEGHAN and ASUNDI (Metadata Framework for Describing Embodied Knowledge and Subject Content) propose to use the Generalized Facet Structure framework which is based an Ranganathan's General Theory of Knowledge Classification as a framework for describing the content of documents in a metadata element set for the representation of web documents. CHUDAMANI (Classified Catalogue as a Tool for Subject Based Information Retrieval in both Traditional and Electronic Library Environment) explains why the classified catalogue is superior to the alphabetic cata logue and argues that the same is true in the digital environment.

- Abstract
- Presents a pilot study for an Internordic project to monitor the use of online catalogues in the Nordic technological university libraries. Focuses on the use of classification in subject searching, how the UDC is used and the extent of its use. Studies user interaction with the OPACs and improvements to information retrieval in the catalogues using the transaction log method to gather data. The pilot study examnines the TENTTU Books database which is the online union catalogue of the Helsinki Univ. of Technology Library, a multilingual database with true information retrieval. The Internordic study itself will make comparisons between the TENTTU system and the new Virginia Tech Library System. Discusses the users monitored, method of analysis, subject searching in the database, results and how the UDC codes were used. Compares this to other studies conducted in Finland and evaluates the project

- Abstract
- Free text searching with keywords in a complete data store is not necessarily the best automatic retrieval method. There must be a proper classification of documents and concepts and the use of a proper classification system avoids problems of terminological deficiency. The dialogue search form makes the on-line catalogue a new information medium. A bibliographic unit must be created with as many search access points as possible, using verbal and classificatory search elements. Verbal search categories must include free text elements for individual search access requirements and a controlled vocabulary with syntactic connections. Classified data should consist of a universal classification system with clear structural notation for access and surface searching, together with several specialist subject classifications for differentiated documentation and retrieval. The universal classification needs no detailed subdivision: it serves mainly as a guide and entry to the detailed sub-systems

- Abstract
- Dewey Decimal Classification has been used to organize materials owned by the three scientific libraries at the University of Pavia, and to allow integrated browsing in their union catalogue through SciGator, a home built web-based user interface. Classification acts as a bridge between collections located in different places and shelved according to different local schemes. Furthermore, cross-discipline relationships recorded in the system allow for expanded queries that increase recall. Advantages and possible improvements of such a system are discussed.

- Abstract
- Once the library has been through a process of transition from traditional library procedures to automated ones, natural language searching became a necessity for both indexers and searchers. Therefore, aside from the precoordinated classified catalogue we started to build a dictionary of terms in order to make postcoordinate search possible in keeping with the UDC notations assigned to each bibliographic record. After a while we came to the conclusion that the dictionary needed a control of its terms so that synonymous concepts and semantic ambuguities be avoided. The project presented in this paper shows how reality imposed the improvement of the quality of indexing and hence of the searching possibilities. Is also shows the reasons why we consider a multilingual thesaurus based on UDC an ideal indexing and searching device. The experiment applied on class 8 of UDC illustrates the way the UDC tables can be quite successfully used in building a thesaurus due to their qulities and how their limitations can be overcome by a thesaurus. An appendix to the paper contains a sample of the multilingual thesaurus given in both alphabetical and systematic layouts

- Abstract
- As librarians increasingly try to use their online catalogues to do what used to be done with their card shelflists, they are realizing that some catalogue sedigners and vendors have not paid enough attention to online shelf order classification access. Compares the call number searching abilities of 8 prominent, mature library systems: VTLS, Inlex, Innovative Interfaces, Inc., Data Research Associates (DRA), Geac Advance, Dynix, SIRSI, and NOTIS. Using 5 criteria that are important to cataloguers, each system was tested and rated for its suitability as an online shelflist. *** Special note from the authors: "[We've] become aware of a new version of SIRSI's Unicorn library system-- version 7.0 that changes our rating of SIRSI in a major way. We had rated SIRSI Unicorn a "C" in the paper, but now we would rate version 7.0 an "A". This is indeed a major change. Fortunately, we identified version numbers for each system in the article: we had tested version 6.1 of SIRSI. Thus, version 7.0 of SIRSI Unicorn, available in early 1995, has improved to the point that it meets every criteria used in the article for suitability as an online shelflist. The authors have evaluated version 7.0 with an "A" rating." ***
