- Abstract
- Although service-oriented architectures go a long way toward providing interoperability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of ontologies. Then we analyze four basic models of semantic interoperability that differ in respect to their mapping between service descriptions and ontologies and in respect to where the evaluation of the integration logic is performed. We also provide some guidelines for selecting one of the possible interoperability models.

- Abstract
- Document representations for text classification are typically based on the classical Bag-Of-Words paradigm. This approach comes with deficiencies that motivate the integration of features on a higher semantic level than single words. In this paper we propose an enhancement of the classical document representation through concepts extracted from background knowledge. Boosting is used for actual classification. Experimental evaluations on two well known text corpora support our approach through consistent improvement of the results.

- Abstract
- The challenge of cataloging Web sites and electronic resources was the most important issue facing the cataloging world in the last year. This article reviews attempts to analyze and revise the cataloging code in view of the new electronic environment. The difficulties of applying traditional library cataloging standards to Web resources has led some to favor metadata as the best means of providing access to these materials. The appropriate education and training for library cataloging personnel remains crucial during this transitional period. Articles on user understanding of Library of Congress subject headings and on cataloging practice are also reviewed.

- Abstract
- Papers on the cataloging of electronic resources have focused on electronic journals and Internet resources such as Web sites and not on electronic books. Electronic books are nonserial monographic resources accessed with a computer either directly or remotely. Rules and standards for cataloging electronic resources have changed and continue to change. This article discusses the electronic book as a unique manifestation and provides practical instruction on the application of current cataloging rules. The cataloging elements covered are control fields and variable data fields, including classification, uniform titles, title information, edition information, type and extent of the resource, publication and distribution information, physical description, series statements, notes, and subject analysis.

- Abstract
- A few years into the development of Cataloger's Desktop, an electronic cataloging tool aggregator available through the Library of Congress, is an opportune time to assess its impact on cataloging operations. A search for online cataloging tools on the Internet indicates a proliferation of cataloging tool aggregators which provide access to online documentation related to cataloging practices and procedures. Cataloger's Desktop stands out as a leader among these aggregators. Results of a survey to assess 159 academic ARL and large public libraries' reasons for use or non-use of Cataloger's Desktop highlight the necessity of developing strategies for its successful implementation including training staff, providing documentation, and managing technical issues.

- Abstract
- The employees of an organization often use a personal hierarchical classification scheme to organize digital documents that are stored on their own workstations. As this may make it hard for other employees to retrieve these documents, there is a risk that the organization will lose track of needed documentation. Furthermore, the inherent boundaries of such a hierarchical structure require making arbitrary decisions about which specific criteria the classification will b.e based on (for instance, the administrative activity or the document type, although a document can have several attributes and require classification in several classes).A faceted classification model to support corporate information organization is proposed. Partially based on Ranganathan's facets theory, this model aims not only to standardize the organization of digital documents, but also to simplify the management of a document throughout its life cycle for both individuals and organizations, while ensuring compliance to regulatory and policy requirements.

- Abstract
- The appearance in OCLC and RLIN of minimal level catalog records from European book vendors for European language monographs and their effect on cataloging department workflows and cooperative cataloging efforts have been matters of concern expressed recently at ALA meetings and in the library literature. A study of 8,778 catalog records was undertaken to discover how many current European language monographs were being cataloged by the Library of Congress, by member libraries, and by vendors. It was found that vendor records accounted for 16. 7% of Spanish books, 18% of French books, 33.6% of German books, and 52.5% of those in Italian. The number of libraries enhancing vendor records in OCLC was found to be only approximately one-third the number of libraries contributing original records for European language books. Ongoing increases in European book publishing and the increasing globalization of cataloging databases mean that the results of this study have implications not only for local cataloging practice but for cooperative cataloging as a whole.

- Abstract
- This paper presents findings of a survey an the state of cataloging and metadata education. in ALA-accredited library and information science progranis in North America. The survey was conducted in response to Action Item 5.1 of the "Bibliographic Control of Web Resources: A Library of Congress Action Plan," which focuses an providing metadata education to new LIS professionals. The study found LIS programs increased their reliance an introductory courses to cover cataloging and metadata, but fewer programs than before had a cataloging course requirement. The knowledge of cataloging delivered in introductory courses was basic, and the coverage of metadata was limited to an overview. Cataloging courses showed similarity in coverage and practice and focused an print mater!als. Few cataloging educators provided exercises in metadata record creation using non-AACR standards. Advanced cataloging courses provided in-depth coverage of subject cataloging and the cataloging of nonbook resources, but offered very limited coverage of metadata. Few programs offered full courses an metadata, and even fewer offered advanced metadata courses. Metadata topics were well integrated into LIS curricula, but coverage of metadata courses varied from program to program, depending an the interests of instructors. Educators were forward-looking and agreed an the inclusion of specific knowledge and skills in metadata instruction. A series of actions were proposed to assist educators in providing students with competencies in cataloging and metadata.

- Abstract
- The Illinois Fire Service Institute Library (FSI Library) has the most comprehensive and popular nonprint fire emergency collection in Illinois. Besides providing descriptive cataloging for nonprint materials, the Library assigns in-depth subject terms and modified Library of Congress Classification to the catalog records. The Library reviewed its subject list and found numerous inconsistencies and duplications, because catalog records are acquired from sources using different subject vocabularies. The Library began a project in August 1999 to map the Library of Congress Subject Headings (LCSH), Medical Subject Headings (MeSH) from the National Library of Medicine, and other fire vocabulary systems. The project developers created FireTalk, a new FSI thesaurus with a mix of LCSH, MeSH terms (identified as such), plus more specific fire science terms. FireTalk is used with the Library's Online Public Access Catalog at the Institute's website to enhance retrieval of relevant bibliographic citations and facilitate multiple database searching.

- 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
- This article describes the use of the World Wide Web as a valuable name authority resource and tool for special collections analytic-level cataloging and the specific goal of fully discovering the names of people who lived in the past as well as those from the present. Current tools and initiatives such as the Name Authority Component of the Program for Cooperative Cataloging (NACO) and the Library of Congress Name Authority File have a specific mission and are partially helpful. Web resources encompassing special collections are often intricate and require global and enhanced resources to continue what have been the guiding principles, tradition, and value of cataloging: to discover works via many points of entry; to find works by or about the same person, topic, or title; and to continue the great cataloging legacies of standards and cooperation.

- Abstract
- A recent change in cataloging at the Library of Congress, and the recent publication of reports calling for broader changes in cataloging generally, have made catalogers wonder about their future, and about what to expect from LC. This article examines LC's historical relations with other libraries, the content of proposals for broad changes in cataloging, the significance for cataloging of commercial "content organizers" such as Google, and expectations from a new Working Group on the Future of Bibliographic Control, commissioned by LC to report in 2007.

- Abstract
- Efficiency and effectiveness of technical services units are difficult to measure, analyze, and compare, partly because operations are complex and vary substantially from one library to another. Cost studies have been widely conducted as a means of measuring the cost efficiency of specific technical services tasks. Since data on costs are not necessarily comparable among institutions, other quantifiable measures of efficiency and effectiveness would enhance managerial decision-making. This article reports the analysis of data compiled from a survey of twenty-six academic libraries. It seeks to supplement the findings of cost studies by providing measures of efficiency and effectiveness for cataloging departments based on reported productivity, number of staff, task distribution, and quality measures such as backlogs, authority control, and database maintenance. Benchmark productivity levels for six libraries with best practices are identified.

- Abstract
- The Library of Congress (LC) has many of the same challenges as other libraries, especially large ones. LC has many different types of resources - books, journals, maps, music, manuscripts, audio, moving image, still image, artifacts, electronic - with large collections of each. Different levels of access are needed for this material: for some, collection level bibliographic description is adequate; for many, item level access is adequate; but for others, such as sound recordings, analytic, or sub unit access is highly desirable.The sizes of the LC collections are a major challenge - over 125 million non-electronic and over 3 million electronic items (and growing rapidly). And finally, electronic resources are presenting us with new issues - from metadata to preservation to storage to linking techniques. LC has tried to approach these challenges from a service perspective. Access must be successful for the end user, which mandates as much coherence and consistency in the metadata as possible and access systems that are easy to use. This paper focuses an the Library of Congress' perspective an metadata in the following three areas: (1) descriptive metadata in our current operations, (2) pathways that are developing that will support possible evolution in the future, and (3) broader metadata needs with digital material. The discussion is from a metadata element set and format point of view, not a cataloging data and cataloging rules view. Most acronyms used in this paper are expanded in an Appendix.

- Abstract
- In this article we present an empirical approach to the study of the statistical properties of bibliometric indicators on a very relevant but not simply available aggregation level: the research group. We focus on the distribution functions of a coherent set of indicators that are used frequently in the analysis of research performance. In this sense, the coherent set of indicators acts as a measuring instrument. Better insight into the statistical properties of a measuring instrument is necessary to enable assessment of the instrument itself. The most basic distribution in bibliometric analysis is the distribution of citations over publications, and this distribution is very skewed. Nevertheless, we clearly observe the working of the central limit theorem and find that at the level of research groups the distribution functions of the main indicators, particularly the journal- normalized and the field-normalized indicators, approach normal distributions. The results of our study underline the importance of the idea of group oeuvre, that is, the role of sets of related publications as a unit of analysis.
