    Abstract
    The quality of large catalogs is uneven and often low, but this issue is underrated and understudied. Library catalogs often fail to communicate correct and clear information to users and their low quality is not simply due to faults, duplications, and so on but also to unwise cataloging standards and policies. While there is plenty of uncontrolled information about books and other publications, the need for good-quality bibliographic information is apparent and library catalogs may provide a trustworthy map of the publishing output, with full control of editions, works, authors, and so on and effective navigation functions, which are lacking in today's information-rich environment.

    Abstract
    In the last decade a discussion has been going an in the Division of Bibliographic Control of the International Federation of Library Associations and Institutions (IFLA) about the principles of cataloguing. This discussion was initiated by the widespread replacement of the card and list catalogues by Online Public Access Catalogues (OPACs) since 1980. In this paper we discuss the role of subject cataloguing in three important documents that are the results of this discussion. Our conclusion is that the interest in subject cataloguing has grown remarkably, but is still not an the level it deserves given the fact that a great part of all searches in OPACs are subject oriented.
    Content
    1. Introduction In this paper we address two questions: 1. What is the position of subject indexing in the thinking of the library world after the publication of the Functional Requirements for Bibliographic Records (1998)? 2. Is this position in accordance with the requirements of the users searching for documents about a given subject? Research Shows that searching an a topic (i.e. subject access) is an important, even predominant type of end-user searching of library catalogues and even more so of other bibliographic databases. Between one third and two thirds of all OPAC searches are probably subject searches (Large & Beheshti, 199%). Taking into account different ways in which searching an a topic is implemented in library catalogues (subject headings, classification, keywords only) the percentage may be even higher. For example title word searching may be a substitute for subject searching if no better tools are available. In the light of this it is not surprising that the Functional Requirements for Bibliographic Records (FRBR) (1998) pays attention to subject searching, as well as the Functional Requirements and Numbering of Authority Records (FRANAR) (2003). Also the Statement of International Cataloguing Principles: Final draft of 19 December 2003, which is the result of the first First IFLA Meeting of Experts an an International Cataloguing Code mentiong subject access as a function of cataloguing (Statement, 2003). In this paper we discuss the ways these three documents deal with subjects.

    Abstract
    The destabilizing influences of the Web, widespread ownership of personal computers, and rising computer literacy have created an era of discontinuous change in research libraries a time when the cumulated assets of the past do not guarantee future success. The library catalog is such an asset. Today, a large and growing number of students and scholars routinely bypass library catalogs in favor of other discovery tools, and the catalog represents a shrinking proportion of the universe of scholarly information. The catalog is in decline, its processes and structures are unsustainable, and change needs to be swift. At the same time, books and serials are not dead, and they are not yet digital. Notwithstanding widespread expansion of digitization projects, ubiquitous e-journals, and a market that seems poised to move to e-books, the role of catalog records in discovery and retrieval of the world's library collections seems likely to continue for at least a couple of decades and probably longer. This report, commissioned by the Library of Congress (LC), offers an analysis of the current situation, options for revitalizing research library catalogs, a feasibility assessment, a vision for change, and a blueprint for action. Library decision makers are the primary audience for this report, whose aim is to elicit support, dialogue, collaboration, and movement toward solutions. Readers from the business community, particularly those that directly serve libraries, may find the report helpful for defining research and development efforts. The same is true for readers from membership organizations such as OCLC Online Computer Library Center, the Research Libraries Group, the Association for Research Libraries, the Council on Library and Information Resources, the Coalition for Networked Information, and the Digital Library Federation. Library managers and practitioners from all functional groups are likely to take an interest in the interview findings and in specific actions laid out in the blueprint.

    Abstract
    This think piece tells why the online library catalog fell from grace and why new directions pertaining to cataloging simplification and primary sources will not attract people back to the online catalog. It proposes an alternative direction that has greater likelihood of regaining the online catalog's lofty status and longtime users. Such a direction will require paradigm shifts in library cataloging and in the design and development of online library catalogs that heed catalog users' longtime demands for improvements to the searching experience. Our failure to respond accordingly may permanently exile scholarly and scientific information to a netherworld where no one searches while less reliable, accurate, and objective sources of information thrive in a paradise where people prefer to search for information.
    The impetus for this essay is the library community's uncertainty regarding the present and future direction of the library catalog in the era of Google and mass digitization projects. The uncertainty is evident at the highest levels. Deanna Marcum, Associate Librarian for Library Services at the Library of Congress (LC), is struck by undergraduate students who favor digital resources over the online library catalog because such resources are available at anytime and from anywhere (Marcum, 2006). She suggests that "the detailed attention that we have been paying to descriptive cataloging may no longer be justified ... retooled catalogers could give more time to authority control, subject analysis, [and] resource identification and evaluation" (Marcum, 2006, 8). In an abrupt about-face, LC terminated series added entries in cataloging records, one of the few subject-rich fields in such records (Cataloging Policy and Support Office, 2006). Mann (2006b) and Schniderman (2006) cite evidence of LC's prevailing viewpoint in favor of simplifying cataloging at the expense of subject cataloging. LC commissioned Karen Calhoun (2006) to prepare a report on "revitalizing" the online library catalog. Calhoun's directive is clear: divert resources from cataloging mass-produced formats (e.g., books) to cataloging the unique primary sources (e.g., archives, special collections, teaching objects, research by-products). She sums up her rationale for such a directive, "The existing local catalog's market position has eroded to the point where there is real concern for its ability to weather the competition for information seekers' attention" (p. 10). At the University of California Libraries (2005), a task force's recommendations parallel those in Calhoun report especially regarding the elimination of subject headings in favor of automatically generated metadata. Contemplating these events prompted me to revisit the glorious past of the online library catalog. For a decade and a half beginning in the early 1980s, the online library catalog was the jewel in the crown when people eagerly queued at its terminals to find information written by the world's experts. I despair how eagerly people now embrace Google because of the suspect provenance of the information Google retrieves. Long ago, we could have added more value to the online library catalog but the only thing we changed was the catalog's medium. Our failure to act back then cost the online catalog the crown. Now that the era of mass digitization has begun, we have a second chance at redesigning the online library catalog, getting it right, coaxing back old users, and attracting new ones. Let's revisit the past, reconsidering missed opportunities, reassessing their merits, combining them with new directions, making bold decisions and acting decisively on them.

    Abstract
    This article identifies and discusses the issues and problems that need to be considered in the process of planning and implementing card-image public access catalogues (CIPACs). CIPACs are online library catalogues based an databases of digitised catalogue cards with more or less sophisticated mechanisms for browsing or searching. Solutions of this kind have been implemented by a number of libraries in various countries since the mid-1990s, mainly as inexpensive alternatives to full retrospective conversion of their old catalogues. Based upon a questionnaire and relevant literature, the article looks at the following aspects: cost, conversion Speed, universal access, saving of space, preservational aspects, Software selection, preparing the card catalogue for conversion, scanning and quality control, image standards, optical character recognition, manual and intellectual input, technological aspects, administrative tools, organisational aspects, peculiarities of old catalogues, presentation of CIPACs to the users, and life expectancy of card-image catalogues.

    Abstract
    Reports results of 2 separate but related projects to study the influence of spelling errors (misspellings), made by searchers, on the subject searching of online catalogues and to suggest ways of improving error detection systems to handle the errors that they detect. This involved the categorization of user queries for subjects that were extracted from the online catalogue transaction logs of 4 USA university libraries. The research questions considered: the prevalence of misspellings in user queries for subjects; and how users respond to online catalogues that detect possible spelling errors in their subject queries. Less than 6% of user queries that match the catalogue's controlled and free text terms were found to contain spelling errors. While the majority of users corrected misspelled query words, a sizable proportion made an action that was even more detrimental than the original misspelling. Concludes with 3 recommended improvements: online catalogues should be equipped with search trees to place the burden of selecting a subject the system instead of the user; systems should be equipped with automatic spelling checking routines that inform users of possibly misspelled words; and online catalogues should be enhanced with tools and techniques to distinguish between queries that fail due to misspellings and correction failures. Cautions that spelling is not a serious problem but can seriously hinder the most routine subject search

    Abstract
    The starting-point of the paper is the debate recently developed in LIS literature about OPAC enhancement and the necessity to design OPACs based on search engines features. Supposed improving tools as relevance ranking and relevance feedback devices are examinated. Possible OPAC development lines, based on theoretical examination of relevance and pertinence concepts, according to Sarácevic view, and following semantics perspectives, are presented. Finally, enhancement of OPACs starting from their inner characteristics is proposed, and a plan to improve semantic search functions while maintaining existing indexing methodologies, that is document conceptual analysis, is outlined.

    Abstract
    An increasing number of library user studies are employing ethnographic techniques as an alternative to more traditional qualitative methods such as surveys. Such techniques, however, are only beginning to see significant application to catalog user studies. Beginning with a discussion of the applied ethnographic method and its current usage within the field of Library and Information Science research, this article will assess methods that have traditionally been applied to studies of catalog users and present the case for the potential of an ethnographic approach for future catalog evaluation and design.
