    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
    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
    Despite the existence of a logical structural model for bibliographic records which integrates any record type, library catalogues persist in offering catalogue records at the level of 'items'. Such records however, do not clearly indicate which works they contain. Hence the search possibilities of the end user are unduly limited. The Functional Requirements for Bibliographic Records (FRBR) present through a conceptual model, independent of any cataloguing code or implementation, a globalized view of the bibliographic universe. This model, a synthesis of the existing cataloguing rules, consists of clearly structured entities and well defined types of relationships among them. From a theoretical viewpoint, the model is likely to be a good knowledge organiser with great potential in identifying the author and the work represented by an item or publication and is able to link different works of the author with different editions, translations or adaptations of those works aiming at better answering the user needs. This paper is presenting an interpretation of the FRBR model opposing it to a traditional bibliographic record of a complex library material.

    Abstract
    Suchmaschinen befinden sich einerseits in einem beständigen Wandel. Andererseits gibt es immer wieder Entwicklungen, die die Suche "auf eine neue Ebene" heben. Eine solche Entwicklung, die wir zurzeit erleben, wird unter dem Label "Next Generation Search Systems" geführt. Der Begriff fasst die Veränderungen durch eine Vielfalt von Geräten und Eingabemöglichkeiten, die Verfügbarkeit von Verhaltensdaten en masse und den Wandel von Dokumenten zu Antworten zusammen.

    Abstract
    Libraries, private and public, offer valuable resources to library patrons. As of today, the only way to locate information archived exclusively in libraries is through their catalogs. Library patrons, however, often find it difficult to formulate a proper query, which requires using specific keywords assigned to different fields of desired library catalog records, to obtain relevant results. These improperly formulated queries often yield irrelevant results or no results at all. This negative experience in dealing with existing library systems turns library patrons away from directly querying library catalogs; instead, they rely on Web search engines to perform their searches first, and upon obtaining the initial information (e.g., titles, subject headings, or authors) on the desired library materials, they query library catalogs. This searching strategy is an evidence of failure of today's library systems. In solving this problem, we propose an enhanced library system, which allows partial, similarity matching of (a) tags defined by ordinary users at a folksonomy site that describe the content of books and (b) unrestricted keywords specified by an ordinary library patron in a query to search for relevant library catalog records. The proposed library system allows patrons posting a query Q using commonly used words and ranks the retrieved results according to their degrees of resemblance with Q while maintaining the query processing time comparable with that achieved by current library search engines.

    Abstract
    Continues the results of the Internet survey of 38 different OPAC systems, this looking at forms of name and cross-references. Tests were conducted to examine results of searching for a personal name, Leonardo da Vinci, and a corporate entered subordinately, under parts of the name which were not the leading element. Many libraries provide no cross-references, and in many cases the presence absence of punctuation in the search string has a significant effect. The effect variation when combined in an Author/Title search is also considered. The also considers the special filing of names beginning Mc, which is almost confined to some British systems, and the interfiling of subject with author entries personal names. A number of recommendations conclude the article.

    Abstract
    Three studies were made of the use of COM catalogues at the University of Toronto and the Mississauga Library System: unobtrusive observations, structured interviews, and a timed-search experiment in reel, fiche and card catalogues. The reel catalogue was found to be the overwhelming favourite, almost as popular in the public library as in the academic library, where 82% of the users reported it to be their preferred form of catalogue. However, for nearly all test questions and searcher types in the timed-search experiment, successful searches required less time in the card catalogue than in either form of the COM catalogues.

    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
    This study explored the functionality of the University of Chicago's faceted catalog, Lens, in respect to monographic series. A user study was designed to evaluate the efficiency of Lens in searching for monographic series and also to determine whether controlled series access in the catalog record improves the search results. The results of the study indicate that while Lens could be considered an adequate tool for searching series that are known to be published under the same title, some changes would make it a better search engine for a series that changes series statements from one volume to another.

    Abstract
    Genre/Form headings are an important means by which librarians provide users with contextual or descriptive information. To facilitate the discovery of resources with important provenance characteristics, the Marion E. Wade Center added terms from a controlled vocabulary to bibliographic records representing items in the C. S. Lewis personal library collection. The selected terms focus on features that have historically been of interest to visitors. The addition of these headings in the bibliographic records allows users to use these keywords to conduct a search or narrow their results, resulting in more flexibility to locate and select the resources that best meet their needs.

    Abstract
    This paper presents the first large-scale investigation of the users and uses of WorldCat.org, the world's largest bibliographic database and global union catalog. Using a mixed-methods approach involving focus group interviews with 120 participants, an online survey with 2,918 responses, and an analysis of transaction logs of approximately 15 million sessions from WorldCat.org, the study provides a new understanding of the context for global union catalog use. We find that WorldCat.org is accessed by a diverse population, with the three primary user groups being librarians, students, and academics. Use of the system is found to fall within three broad types of work-task (professional, academic, and leisure), and we also present an emergent taxonomy of search tasks that encompass known-item, unknown-item, and institutional information searches. Our results support the notion that union catalogs are primarily used for known-item searches, although the volume of traffic to WorldCat.org means that unknown-item searches nonetheless represent an estimated 250,000 sessions per month. Search engine referrals account for almost half of all traffic, but although WorldCat.org effectively connects users referred from institutional library catalogs to other libraries holding a sought item, users arriving from a search engine are less likely to connect to a library.
