Abstract

Purpose - The purpose of this article is to outline the approach taken to the reclassification of the library collection within a small multi-site college of higher education - whereby 160,000 volumes were converted from the BLISS system to the Dewey Decimal Classification system, over a period of 11 weeks during Summer 2004. Design/methodology/approach - An automated approach was taken whereby the Library Systems Supplier - Talis was commissioned to convert catalogue records using a batch process. Risk analysis and critical path analysis were used as tools to keep the project on schedule and provide quality control. Findings - An automated approach allowed the project to be completed on time, within budget and with minimal disruption to services. Project planning was crucial to the success of the project. This included mapping BLISS to Dewey numbers, recruitment of a student team, management of work packages and ensuring continuity of the Library Service during the project. Practical implications - Institutional support for the project was secured because of its relevance to the College's corporate agenda and the promise of a wider impact that the project would have in terms of modernisation of the library service. Originality/value - Despite the apparent lack of current articles on re-classification, many libraries are still grappling with ongoing retrospective cataloguing projects. This case study demonstrates how one institution approached the problem and demonstrates that an automated approach can yield benefits. It will be of use to other libraries thinking of, or involved with, similar conversions. The partnership role of the Library Management System Supplier is also highlighted.

Abstract

In the last 10 years a number of libraries in the Netherlands have developed akternative shelf arrangements to the standard SISO system. A survey undertaken at Felde children's library following the implementation of an alternative arrangement showed that children had been unaware of the change. In 1989 the Nederlands Bibliothekk en Lektuur Centrum (Dutch Centre for Libraries and Reading) began developing a system based on trials at 15 libraries. Further implementations of the system should take account of developments with automated catalogues

Abstract

This paper focuses on the job undertaken between 2003 and 2004 in order to plan a new location arrangement for the Philosophy collection of one of the libraries at the University of Trieste. The paper describes the basic needs which played a fundamental role in the planning phase. Furthermore, it examines in detail how the most widely known classification systems - particularly the DDC- did not seem the best answer to the specific needs in this context. The solution was to develop an original classification system in order to answer the specific needs. The paper describes its development and the basis upon which it was built: the classification schemes used were those of the most authoritative periodical bibliographies in this field. Among them, the International Philosophical Bibliography system seemed to be closer to the continental tradition of the organization of knowledge in the discipline. Conclusions deal with the management of the transition from the old to the new system giving some information about the possible evaluation of the work that has been carried out.

Abstract

The ongoing project to revise the arrangement of the open shelves library collections occasioned a historiographic account of the implementation phases of the Library of Congress Classification (LCC), subclasses B-BJ - Philosophy and Psychology, at the Library of the Department of Philosophy of the University of Padua (Italy). The schema was adopted as a collection shelving and location device since the Library institution in 1997. The LCC international acknowledgement and the neutral framework of the schema have undoubtedly played a role of driving factors at the first stage of the selection process. However, the implementation of the classification scheme had to consider critical issues like the shortage of the library area, the selection criteria of the appropriate bibliographic material, as well as the effort to settle and tailor the original schema to the specific needs of the library collections and its end-users. The purpose of this paper is twofold: from one hand, we aim to examine in detail each stage of the implementation project in order to provide a preliminary impact evaluation of the classification schema both on the collections management and development and on the research practices of the local users community; from the other, we intend to highlight the principal factors that have implied a sort of declassification process of the system itself. In conclusion, we argue that the declassification of library collections can be read, from a bottom-up perspective, as index of vitality of the collections themselves, as well as a valuable basis for planning the next steps of the Library project.

Abstract

Patrons often browse through books organized by a library classification system, looking for books to use and possibly circulate. This research is an examination of the clustering of similar books provided by a classification system and ways in which the books that patrons circulate are clustered. Measures of classification system performance are suggested and used to evaluate two test collections. Regression formulas are derived describing the relationships among the number of areas in which books were found (the number of stops a patron makes when browsing), the distances across a cluster, and the average number of books a patron circulates. Patrons were found usually to make more stops than there were books found at their average stop. Consequences for full-text document systems and online catalogs are suggested

Abstract

This article presents a new idea on shelving printed books and finding books in libraries. The author advocates that traditional book classification number (TBCN) systems should be replaced by a better indexing method for books in libraries. The author proposes a new way of seeking books for library users wishing to locate them called a 'dynamic book subject number' (DBSN) system. The new system combines new indexing rules and automated system technology to create settings in which a book's 'subject number' can change rather than having a particular permanent classification number assigned to it. The new way encourages library users to seek books through a user-friendly cataloging system by choosing subjects from the embedded database. The database contains thousands of subjects with their corresponding Arabic codes. For printed books, the DBSN ushers in a new era in the relationship between library users and the books.

Abstract

Shelf arrangement, from a bibliographic perspective, constitutes a reading proposal of the collection to the users as well as a resource for management and access to the documents. However, the centrality of the call number testifies the near forgetfulness of the different proposals that came before it and the role of the collection of documents and the target audience in the elaboration of the organization, in addition to the overlapping of the bibliographic classification to shelf arrangement. This work is justified by the need to restore shelf arrangement, seeking to understand its fundamental aspects from the literature in which the activity was systematized. Thus, this paper aims at contributing to reorient the shelf arrangement as an activity of information organization, exploring its conformation in the Francophone literature, from the midnineteenth century up to the 1930s. As for the methodology, this is an exploratory research made possible through the historical-conceptual investigation of shelf arrangement found in the Francophone manuals of librarianship of that period. This study concludes that the activity was placed by that line since the nineteenth century, when its own terminology was developed under the consideration of the intervention of the contexts, using methods and guided by the diversity of proposals.

Abstract

With more than a million books published each year, thousands of books will be cataloged and shelved in libraries. Assigning book numbers efficiently and balancing the distribution of main entries over the LC Cutter Table entries have become critical issues for shelving later entries in libraries using the Library of Congress Classification (LCC) system. This paper aims to explore and discuss the problems in assigning book numbers (Cutter numbers) to printed materials under the LCC System. The existing problems have blocked or invaded the usage of some numbers and letters ruled by the LC Cutter Table. The reason is either not following the LC Cutter Table well, or confusion in using the Table. Directly downloading the LC record to the local database adds more questions to the issue.

Abstract

The Philosophy Library at the University of Milan was born in the fifties by the merger of the two Institutes of Philosophy and the History of Philosophy. Once the restoration had been completed, it was necessary to devise a suitable classification system in order to arrange the books and to meet the new research needs of the Institutes. The project was untrusted to Prof. Corrado Mangione and Prof. Maria Assunta del Torre, with the theoretical contribution of Giuliana Sapori, chief Director of Central Library of the Faculty of Laws and Humanities. The model had been conceived as completely anew, without any reference toother existing classification systems. The inspiring principles were from one hand the choice for an open shelving system, from the other one the idea that the orientation criteria and the book search had to be user-friendly for everyone. This paper provides an in-depth analysis of the making-up of the call number as applied to each section of the collection, and how the scheme has been developed over the past fifty years. Points of strenght and weakness of the scheme are also discussed at the light of the technological innovations which have gradually affected the whole of the library activities, notably with the introduction of the electronic catalogue. The original classification scheme has maintened its coherence and functionality over time, in spite of the expansion of the collection and the automation of all stages of the classification process. This is the main reason to keep using it in the future.
