Multiple studies have illustrated that the needs of various users seeking descriptive bibliographic data for pop culture resources (e.g. manga, anime, video games) have not been properly met by cultural heritage institutions and traditional models. With a focus on manga as the central resource, the purpose of this paper is to address these issues to better meet user needs.

Based on an analysis of existing bibliographic metadata, this paper proposes a unique bibliographic hierarchy for manga that is also extendable to other pop culture sources. To better meet user requirements of descriptive data, an aggregation-based approach relying on the Object Reuse and Exchange-Open Archives Initiative (OAI-ORE) model utilized existing, fan-created data on the web.

The proposed hierarchy is better able to portray multiple entities of manga as they exist across data providers compared to existing models, while the utilization of OAI-ORE-based aggregation to build and provide bibliographic metadata for said hierarchy resulted in levels of description that more adequately meet user demands.

Though studies have proposed alternative models for resources like games or comics, manga has remained unexamined. As manga is a major component of many popular multimedia franchises, a focus here with the intention while building the model to support other resource types provides a foundation for future work seeking to incorporate these resources.

This paper reports two experiments that investigated the semantic distance model (SDM) of relevance assessment. In the first experiment graduate students of mathematics and economics assessed the relevance relationships between bibliographic records and hierarchies of terms composed of classification headings or help‐menu terms. The relevance assessments of the classification headings, but not the help‐menu terms, exhibited both a semantic distance effect and a semantic direction effect as predicted by the sdm. Topical subject expertise enhanced both these effects. The second experiment investigated whether the poor performance of the help‐menu terms was an experimental design artifact reflecting the comparison of terse help terms with verbose classification headings. In the second experiment the help‐menu terms were compared to a hierarchy of single‐word terms where they exhibited both a semantic distance and semantic direction effect.

This paper focuses on the way users navigate bibliographic families not only when a user has no specific document in mind but also when he/she has a specific predefined need in mind.

To this end, the Epic of Kings was selected as a test-bed for the study and both situations were studied based on International Federation of Library Associations and Institutions-Library Reference Model (IFLA-LRM), but the potential users (participants of this study) were not directly exposed to the entities of the model. Card sorting, interview and distributing questionnaire constituted the data-gathering process.

Almost all of the participants in this study, when they had no specific resource in mind, generated a top-down view of the family, and in this view, all of them disregarded the item entity and lots of them disregarded the manifestations also. Yet on the other side, when they were asked to assume themselves in certain situations (in need of a specific work with a predefined expression and format), they viewed the bibliographic family from a bottom-up approach.

Most of the studies in this area regard the navigation process of users as a top-down approach and the Functional Requirements for Bibliographic Records (FRBR) family as a model suitable for hierarchical top-down visualization of bibliographic families. Yet this study poses the bottom-up approach of users regarding the family.

A strong definition of aboutness and a theory of its role in information retrieval systems have not been developed. Such a definition and theory may be extracted from the work of T. A. van Dijk. This paper discusses some of the implications of van Dijk's work for bibliographic classification theory. Two kinds of intertextuality are identified: that between documents classified in the same class of the same classification system; and that between the classification system as a text in its own right and the documents that are classified by it. Consideration of the two kinds of intertextuality leads to an investigation of the linguistic/cognitive processes that have been called the ‘translation’ of a document topic into a classificatory language. A descriptive model of the cognitive process of classifying documents is presented. The general design of an empirical study to test this model is suggested, and some problems of implementing such a study are briefly identified. It is concluded that further investigation of the relationships between text linguistics and classification theory and practice might reveal other fruitful intersections between the two fields.

The current library bibliographic infrastructure was constructed in the early days of computers – before the Web, XML, and a variety of other technological advances that now offer new opportunities. General requirements of a modern metadata infrastructure for libraries are identified, including such qualities as versatility, extensibility, granularity, and openness. A new kind of metadata infrastructure is then proposed that exhibits at least some of those qualities. Some key challenges that must be overcome to implement a change of this magnitude are identified.

Attempts to introduce a new approach for describing bibliographic entities in order to fulfil all the functions of the catalogue in the online environment. While it is assumed that the basic unit of description is the item in hand and records describing items would fulfil the finding, identifying, choosing and locating functions; super records, which are based on the concept of “super works”, would fulfil the collocating function in a more meaningful way. This approach is a solution to the problem of the same work appearing in various manifestations and formats. Super records for voluminous works include attributes that are common to different versions of a work and are linked to bibliographic records for items. A prototype catalogue of super records has been developed and made available on the Web to introduce the advantages, limitations and possible consequences of the concept on cataloguing principles, MARC and Z39.50.

This article considers the impact of the IFLA Functional Requirements for Bibliographic Records (FRBR), the implications of FRBR for cataloguing and the impact of FRBR on MARC and the Anglo‐American Cataloguing Rules (AACR). The article also considers the effects of FRBR on the Paris Principles, in the context of the proposed International Cataloguing Code (ICC). It stresses the importance of maintaining a clear statement of principles and values.

Web‐OPACs not only offer simplified access to library holdings for end‐users but also enable librarians to add value to their catalogue data. One feature which has become almost a standard for new library software is including links to full‐text or multimedia documents corresponding to a particular citation. Other features which have not yet become common but will soon do so include: links to publishers, links to corporate sources, and links to journal titles. The latter usually provide tables of contents, and sometimes also offer direct access to full‐text documents for subscribers. Online database providers have acknowledged these new possibilities, librarians soon will. So when migrating library software to new products or new releases, such issues should be observed.

The goal of this paper is to propose a data access control framework that is used for editing MARC‐based bibliographic databases. In cases where the bibliographic record editing activities carried out in libraries are complex and involve many people with different skills and expertise, a way of managing the workflow and data quality is needed. Enforcing access control can contribute to these goals.

The proposed solution for data access control enforcement is based on the well‐studied standard role‐based access control (RBAC) model. The bibliographic data, for the purpose of this system, is represented using the XML language. The software architecture of the access control system is modelled using the Unified Modelling Language (UML).

The access control framework presented in this paper represents a successful application of concepts of role‐based access control to bibliographic databases. The use of XML language for bibliographic data representation provides the means to integrate this solution into many different library information systems, facilitates data exchange and simplifies the software implementation because of the abundance of available XML tools. The solution presented is not dependent on any particular XML schema for bibliographic records and may be used in different library environments. Its flexibility stems from the fact that access control rules can be defined at different levels of granularity and for different XML schemas.

This access control framework is designed to handle XML documents. Library systems that utilise bibliographic databases in other formats not easily convertible to XML would hardly integrate the framework into their environment.

The use of an access control enforcement framework in a bibliographic database can significantly improve the quality of data in organisations where record editing is performed by a large number of people with different skills. The examples of access control enforcement presented in this paper are extracted from the actual workflow for editing bibliographic records in the Belgrade City Library, the largest public city library in Serbia. The software implementation of the proposed framework and its integration in the BISIS library information system prove the practical usability of the framework. BISIS is currently deployed in over 40 university, public, and specialized libraries in Serbia.

A proposal for enforcing access control in bibliographic databases is given, and a software implementation and its integration in a library information system are presented. The proposed framework can be used in library information systems that use MARC‐based cataloguing.

One of the biggest concerns of modern information retrieval systems is reducing the user effort required for manual traversal and filtering of long matching document lists. Thus, the first goal of this research is to propose an improved scheme for representation of search results. Further, it aims to explore the impact of various user information needs on the searching process with the aim of finding a unified searching approach well suited for different query types and retrieval tasks.

The BoW online bibliographical catalogue is based on a hierarchical concept index to which entries are linked. The key idea is that searching in the hierarchical catalogue should take advantage of the catalogue structure and return matching topics from the hierarchy, rather than just a long list of entries. Likewise, when new entries are inserted, a search for relevant topics to which they should be linked is required. Therefore, a similar hierarchical scheme for query‐topic matching can be applied for both tasks.

The experiments show that different query types used for the above tasks are best treated by different topic ranking functions. To further examine this phenomenon a user study was conducted, where various statistical weighting factors were incorporated and their impact on the performance for different query types was measured. Finally, it is found that the mixed strategy that applies the most suitable ranking function to each query type yielded a significant increase in precision relative to the baseline and to employing any examined strategy in isolation on the entire set of user queries.

The main contributions of this paper are: the alternative approach for compact and concise representation of search results, which were implemented in the BoW online bibliographical catalogue; and the unified or mixed strategy for search and result representation applying the most suitable ranking function to each query type, which produced superior results compared to different single‐strategy‐based approaches.
