    Abstract
    Purpose - The purpose of this paper is to explore the information needs of one user group, public library fiction readers, in order to reveal a design of an online community at the local level. Examination of user-generated metadata can reveal new approaches to information architecture. Design/methodology/approach - A literature review into behaviors of virtual communities; surveying public library readers regarding search behavior characteristics - the survey included a sample "tagging" exercise to determine whether public library communities could create meaningful metadata for retrieval purposes. Findings - The use of relevance as an indicator of tag quality is flawed: in a survey, public library readers "tagged" the novel The Da Vinci Code. The resulting collection of tags provided a richer description of the book than did the social book-related web site www.librarything.com. Tag collections can be broken down into different categories, each reflecting a different "facet" of the novel: character, plot, subject/topic, setting, and genre. Faceted structure to tags enables users to choose the context of the tag to the novel. Research limitations/implications - This research is relevant in the world of social networking sites, online communities, or any other such system where users generate descriptive metadata. Examination of such metadata can reveal facets, which can guide the architect/librarian in the design of a versatile architecture. Originality/value - This research resulted in a manifold design for a public-library-based online community that allowed for the full expression of users' information needs. This research introduces a faceted structure to current approaches for user-generated metadata, adding versatility to search terms.

    Abstract
    Stanford University's Socrates II and University of California at Berkeley's Pathfinder are 2 USA World Wide Web based online publication access catalogues under development. They differ in their design language (how an interface functionally and visually communicates to the users). Evaluates each system's interface design and their ability to communicate functionality to users: analyzes design in terms of: colour, buttons, metaphors, layout, and basic and advanced search modes. Concludes that the design languages of both systems have the right directive and have the potential to evolve

    Abstract
    Purpose - Library online public access catalogues (OPACs) are considered to be unattractive in comparison with popular internet sites. In 2000, the authors presented some suggestions on how library catalogues should change. Have librarians actually made their OPACs more user-friendly by adopting techniques and technologies already present in other information resources? This paper aims to address these issues. Design/methodology/approach - The characteristics of four OPACs, one online bookstore and two internet search engines are analyzed. The paper reviews some of the changes and directions suggested by researchers and adds some of authors own. All this is in the hope that library catalogues will survive "Google attack." Findings - Changes are identified in the information services studied over a seven-year period. Least development is found in library catalogues. Suggestions are made for library catalogues of the future. Research limitations/implications - A library catalogue, a web search engine and an internet bookstore cannot be compared directly because of differences in scope. But features from each could be fruitfully used in others. Practical implications - OPACs must be both attractive and useful. They should be at least as easy to use as their competitors. With the results of research as well as the knowledge librarians have many years, the profession should be able to develop better OPACs than we have today and regain lost ground in the "competition" for those with information needs. Originality/value - A comparison of OPAC features in 2000 and 2007, even if subjective, can provide a panoramic view of the development of the field.

    Abstract
    Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

    Abstract
    Library OPACs have long been the gateways between users and information. They present to users the achievements of library automation, and are the most widely available automated retrieval systems and the first that many user encounter. Current trends in OPAC design are toward a user oriented, individual information service which can meet the different needs of users with a variety of background and interests. Compared with the rather inactive, short term and general information service of conventional systems, this type of system focuses on active, long term and personalized service. Proposes a framework for the design of such an OPAC and discusses some recent developments in personalized information service

    Abstract
    It's clear that today's typical library users are Web-sawy and have very high expectations. Librarians need to offer interfaces on Web sites that match or exceed those found on the commercial Web. Paired with high-quality content that's selected and created by librarians, a state-of-the-art Web interface is a compelling destination for users.

    Abstract
    Analyses the OPAC at the Australian Catholic University in New South Wales, Castle Hill Campus using an object oriented model following Rumbaugh's methodology, as described in 'Object oriented modelling and design, 1991'. The process of analysis, although difficult, is one of the most effective ways of determining each function of a system of this kind. The methodology is especially useful as the data structure, behavioural and functional aspects of the system are displayed in separate diagrams. This is an advantage for those analysing systems, who can display many factors without confusing different aspects involved in the analysis process

    Abstract
    Recording for the Blind and Dyslexic has been providing audio recordings of educational texts since 1948. In 1992, it initiated a project to develop an OPAC to allow institutional providers and individual borrowers to search its holdings of over 80.000 volumes. In 1993, a coordinated pilot project was begun to allow a limited test group of institutional sites and individuals the ability to use the catalogue ordering mechanism for document delivery. Describes the project concluding that, although the project was not considered a success, much insight was gained as a result of the efforts which will be of value in the development of an improved version of the OPAC

    Abstract
    Reports results of an online survey of in house users acessing California University's computerized union catalogue, the MELVYL library system, from public access terminals in the libraries of the California University at Santa Cruz (UCSC). The study included descriptive statistics on user status, affiliation, anticipated focus of system usage, judgement of ease of system use, and need for assistance. The transaction logs of respondents to the survey were analyzed and cross tabulated with demographic data on the same group of users. Particular attention was given to subject searching and to the dilemmas that confront users of a system in which heuristics are largely absent. Data was compared with similar data collected in a earlier study of user who accessed the MELVYL library system from remote sites

    Abstract
    FirstSearch is an on-line reference product from OCLC, launched in Oct. 91, that offers inexperienced end users searches easy access to on-line data bases through a simple menu interface. The flagship data base on the OCLC FirstSearch system is the Online Union Catalogue (Called WorldCat on FirstSearch). 14 data bases are available at time of press with a further 18 planned by the end of 1992. Although pricing of OCLC'a EPIC service is based on the standard connect time and display charges, the need for more predictable methods of charging led to FirstSearch use being sold in blocks of 500 searches. Bulk buying of blocks reduces the price per search from 90 cents (for 1 block) to 45 cents (from 160 blocks and above). Describes the experiences of Allen County Public Library, Indiana, one of the only 2 public libraries among the 16 initial test sites for FirstSearch

    Abstract
    As we seek both to improve public school education in high technology areas and to link libraries and classrooms on the 'information superhighway', we need to understand more about children's information searching abilities. We present results of 4 experiments conducted on 4 versions of the Science Library Catalog (SLC), a Dewey Decimal based hierarchical browsing systems implemeted in HyperCard without a keyboard. The experiments were conducted over a 3-year period at 3 sites, with 4 databases, and with comparisons to 2 different keyword online catalogs. Subjects were ethnically and culturally diverse children aged 9 through 12; with 32 to 34 children participating in each experiment. Children were provided explicit instruction and reference materials for the keyword systems but not for the SLC. The number of search topics matched was comparable across all systems and all experiments; search times were comparable, thought hey varied among the 4 SLC versions and between the 2 keyword OPACs. The SLC overall was robust to differences in age, sex and computer experience. One of the keyword OPACs was subject to minor effects of age and computer experience; the other was not. We found relationships between search topic and system structure, such that the most difficult topics on the SLC were those hard to locate in the hierarchy, and those most difficult on the keyword OPACs were hard to spell or required children to generate their own search terms. The SLC approach overcomes problems with several searching features that are difficult for children in typical keyword OPAC systems; typing skills, spelling, vocabulary, and Boolean logic. Results have general implications for the desing of information retrieval systems for children

    Abstract
    The effect that content and layout of bibliographic displays had on the ability of end-users to process catalog information was tested using a 2 x 2 factorial experimental design. Participants were asked to perform two related tasks during the course of the experiment. In the first task, they were asked to select a set of items that they would examine further for a hypothetical paper they must write, using a simulated online catalog to make their assessments of relevance. In the second task, they were asked to examine 20 bibliographic records, decide whether they would choose to examine these items further on the shelf, and identify the data elements that they used to formulate their relevance decision. One group viewed bibliographic records on an interface similar to current online catalogs, one that used data labels and contained data elements commonly found. A second group viewed these records on an interface in which the labels had been removed, but the data elements were the same as those in the first. The third group viewed these records on a labeled display that included enhanced data elements on the brief record display. The final group viewed these records with the same brief record data elements as the third group, but with the labels removed, using ISBD and AACR2 punctuation standards. For the first task, participants using enhanced brief screen interfaces viewed more brief screens and fewer full screens than their counterparts. Screen durations for the second 10 screens were found to have dropped from those of the first 10 screens. Statistical analyses comparing demographic variables to the screen frequencies uncovered many significant differences. Participants using the enhanced-content interfaces made fewer selections from index and full screens, and more selections from brief screens. For the second task, participants who used enhanced-content interfaces were able to make some sort of relevance judgment more frequently than those who used standard-content interfaces.
