    Abstract
    This study examines problems caused by initial articles in library catalogs. The problematic records observed are those whose titles begin with a word erroneously considered to be an article at the retrieval stage. Many retrieval algorithms edit queries by removing initial words corresponding to articles found in an exclusion list even whether the initial word is an article or not. Consequently, a certain number of documents remain more difficult to find. The study also examines user behavior during known-item retrieval using the title index in library catalogs, concentrating on the problems caused by the presence of an initial article or of a word homograph to an article. Measures of success and effectiveness are taken to determine if retrieval is affected in such cases.

    Abstract
    An Internet survey of 38 different OPAC systems, at eighty different libraries, was undertaken to investigate the effect on retrieval of the presence of the hyphen or the ampersand in titles. Title and Keyword searches were performed. In Title search, 22 of the systems treat the hyphen as equivalent to a space, while in Keyword the number is 16. The other systems treat it in various different ways (even including the equivalent of NOT), which means that results of searching multiple catalogs are very inconsistent. The ampersand may be ignored, treated as a special character, or treated as "and," again with very inconsistent results. Various recommendations are made with a view to improving consistency of performance.

    Abstract
    A discussion of the importance of clear cataloguing policies and routines as the basis of quality control, in relation to the methods used in the College of Mexico Library. The fundamental principle is to prevent errors occuring rather than to correct them subsequently. Indices of quality and effiency in relation to errors which do and do not affect retrieval, established through monthly review of samples of the work of each cataloguer, are used to monitor activities and ensure high standards. This process, essentially collaborative, promotes an overall culture of quality

    Abstract
    Describes the results of research to determine the extent of spelling errors in the State University of New York at Albany's online catalogue, whether these errors seriously affect users' access to library materials and what effect spelling errors will have on the group database planned for the State University of New York (SUNY). Using standard database tests, the catalogues of the four SUNY University Centers (Albany, Binghamton, Buffalo and Stony Brook) were studied. In addition, two comparison catalogues were studied: the New York State Library's Excelsior and California University's Melvyl. Results show that misspellings are unavoidable due to the way that most catalogues were built. These errors, however, are rarely an impediment to retrieval. Concludes with suggested ways to find and correct misspellings without expensive large scale efforts

    Abstract
    Pays tribute to the recent advances in the ability to access computerized catalogues from the desktop via the Internet but emphasizes that there are problems still to be overcome before the ideal of universal access to catalogue records for UK libraries is achieved. Advances in computerized cataloguing over the past 40 years have been an obstacle to retrospective cataloguing in a coherent and standardized manner which even the adoption of common standards for information retrieval and the Z39.50 protocol have failed to prevent. Many libraries with modern methods for cataloguing new materials still have earlier sequences of records on microfiche or other hard copy format. Other specialized collections are such that they have never been catalogued to professional standards or in a convenient format. Illustrates the point with reference to practical searching of catalogues in Aberystwyth, Wales, and to 2 studies of the logistical and financial issues of a programme of retrospective cataloguing as reported in BLRIC report 53. Discusses the proposed UK coordinating body and coordinated natioanl prgramme, to select which catalogues should be converted, set priorities for work, ensure maintenance of requisite standards, and arrange collaboration between neighbouring or related institutions

    Abstract
    Users' preferences for folders versus tags was studied in 2 working environments where both options were available to them. In the Gmail study, we informed 75 participants about both folder-labeling and tag-labeling, observed their storage behavior after 1 month, and asked them to estimate the proportions of different retrieval options in their behavior. In the Windows 7 study, we informed 23 participants about tags and asked them to tag all their files for 2 weeks, followed by a period of 5 weeks of free choice between the 2 methods. Their storage and retrieval habits were tested prior to the learning session and, after 7 weeks, using special classification recording software and a retrieval-habits questionnaire. A controlled retrieval task and an in-depth interview were conducted. Results of both studies show a strong preference for folders over tags for both storage and retrieval. In the minority of cases where tags were used for storage, participants typically used a single tag per information item. Moreover, when multiple classification was used for storage, it was only marginally used for retrieval. The controlled retrieval task showed lower success rates and slower retrieval speeds for tag use. Possible reasons for participants' preferences are discussed.

    Abstract
    Works are key entities in the universe of recorded knowledge. Works are those deliberate creations (known variously as opera, oeuvres, Werke, etc.) that constitute individual sets of created conceptions that stand as the formal records of knowledge. In the information retrieval domain, the work as opposed to the document, has only recently received focused attention. In this paper, the definition of the work as an entity for information retrieval is examined. A taxonomic definition (that is, a definition built around a taxonomy) is presented. An epistemological perspective aids in understanding the components of the taxonomic definition. Works, thus defined as entities for information retrieval, are seen to constitute sets of varying instantiations of abstract creations. These variant instantiations must be explicitly identified in future systems for documentary information retrieval. An expanded perception of works, such as that presented in this paper, helps us understand the variety of ways in which mechanisms for their control and retrieval might better be shaped in future.

    Abstract
    Die Universitäts- und Landesbibliothek Münster (ULB Münster) hat jetzt ihre letzten beiden großen konventionellen Kataloge für Literatur bis 1990 im Netz veröffentlicht, den Zentralkatalog der Institute (ZKI) und den Systematischen Katalog (SyK) der ULB. Mit dem ZKI komplettiert die Bibliothek den elektronischen Gesamtnachweis der Literaturbestände in der Universität. Bislang boten der zentrale Online-Katalog (OPAC) und der Online-Katalog der Institute (OKI) bereits 4,2 Mill. Bände für die elektronische Recherche an. Im ZKI kommen nun 1,5 Mill. Bände aus den Instituts- und Seminarbibliotheken hinzu. Der 1990 durch die Online-Schlagwortkatalogisierung nach RSWK abgelöste Systematische Katalog (SyK) erschließt die Bestände der Zentralbibliothek nach Universeller Dezimalklassifikation (UDK). Die digitalisierten Katalogzettel von ZKI (1,05 Mill.) und SyK (1,4 Mill.) sind auf dem Bildschirm als Abbilder (images) der Originale zu sehen, da bei der Digitalisierung die kostengünstige Bildkonvertierung der Katalogkarten im Scan-Verfahren (image scanning) angewandt wurde. Im digitalisierten ZKI werden die bisherigen Recherchemöglichkeiten ins elektronische Medium transportiert und verbessert. Die Suche ist nicht nur jederzeit und allerorts möglich, sie wird auch insgesamt transparenter, übersichtlicher und deutlich schneller. Bereits die Einbindung ins Katalogmenü der ULB mit seinen Kurzinformationen verschafft Orientierung über die Reichweite und den Stellenwert einer ZKI-Recherche im Kontext der alphabetischen Titelnachweise an der Universität.

    Abstract
    Information seeking is a fundamental human activity. In the modern world, it is frequently conducted through interactions with search systems. The retrieval and comprehension of information returned by these systems is a key part of decision making and action in a broad range of settings. Advances in data availability coupled with new interaction paradigms, and mobile and cloud computing capabilities, have created a broad range of new opportunities for information access and use. In this comprehensive book for professionals, researchers, and students involved in search system design and evaluation, search expert Ryen White discusses how search systems can capitalize on new capabilities and how next-generation systems must support higher order search activities such as task completion, learning, and decision making. He outlines the implications of these changes for the evolution of search evaluation, as well as challenges that extend beyond search systems in areas such as privacy and societal benefit.

    Abstract
    Popular commercial on-line services such as Google, e-Bay, Amazon, and Netflix have evolved quickly over the last decade to help people find what they want, developing information retrieval strategies such as usefully ranked results, spelling correction, and recommender systems. Online library catalogs (OPACs), in contrast, have changed little and are notoriously difficult for patrons to use (University of California Libraries, 2005). Over the past year (June 2005 to the present), the Melvyl Recommender Project (California Digital Library, 2005) has been exploring methods and feasibility of closing the gap between features that library patrons want and have come to expect from information retrieval systems and what libraries are currently equipped to deliver. The project team conducted exploratory work in five topic areas: relevance ranking, auto-correction, use of a text-based discovery system, user interface strategies, and recommending. This article focuses specifically on the recommending portion of the project and potential extensions to that work.

    Abstract
    Auf dem Hintergrund der aktuellen OPAC-Entwicklung in Deutschland werden im ersten Teil einzelne Aspekte des OPAC-Designs kommentiert. Es wird u.a. auch auf Möglichkeiten einer Standardisierung der Schnittstelle Retrieval-Software / Benutzeroberfläche eingegangen. Die derzeit dominierenden Online-Kataloge sind für eine Massenbenutzung nur bedingt geeignet, da sie in hohem Maße fehlerintolerant sind, eine Analyse nach Suchfeldern verlangen und mit grundsätzlichen Mängeln der Boole'schen Suchlogik behaftet sind. Im zweiten Teil werden werden Alternativen diskutiert, zum einen in Form eines alphabetisch sortierten Online-Katalogs, zum anderen in Form intelligenter bibliographischer Auskunftssysteme, die Ähnlichkeitssuchen bzw. sog. 'Closest-Match-Suchen' gestatten. Hierzu werden verschiedene Konzepte und Vorschläge vorgestellt
