Abstract

There is currently a lively debate about the role of the library catalogue and its relationship to other resource discovery tools. An example of this debate is the recent publication of a report commissioned by the Library of Congress on "the changing nature of the catalogue" As part of this debate, the role of union catalogues is also being re-examined. Some commentators have suggested that union catalogues, by virtue of their size, can aggregate both supply and demand, thus increasing the chance that a relatively little-used resource will be discovered by somebody for whom it is relevant. During the past year, the National Library of Australia (NLA) has been considering the future of its catalogue and its role in the resource discovery and delivery process. The review was prompted, in part, by the redevelopment of the Australian union catalogue and its exposure on the web as a free public service, badged as Libraries Australia. The NLA examined the enablers and inhibitors to proposition "that it replace its catalogue with Libraries Australia, as the primary database to be searched by users". Flowing from this review, the NLA is aiming to undertake a number of tasks to move in the medium to long term towards a scenario in which it could deprecate its local catalogue.

Bill Howe and his colleagues at the University of Washington, in Seattle, decided to find out. First, they trained a computer algorithm to distinguish between various sorts of figures-which they defined as diagrams, equations, photographs, plots (such as bar charts and scatter graphs) and tables. They exposed their algorithm to between 400 and 600 images of each of these types of figure until it could distinguish them with an accuracy greater than 90%. Then they set it loose on the more-than-650,000 papers (containing more than 10m figures) stored on PubMed Central, an online archive of biomedical-research articles. To measure each paper's influence, they calculated its article-level Eigenfactor score-a modified version of the PageRank algorithm Google uses to provide the most relevant results for internet searches. Eigenfactor scoring gives a better measure than simply noting the number of times a paper is cited elsewhere, because it weights citations by their influence. A citation in a paper that is itself highly cited is worth more than one in a paper that is not.
As the team describe in a paper posted (http://arxiv.org/abs/1605.04951) on arXiv, they found that figures did indeed matter-but not all in the same way. An average paper in PubMed Central has about one diagram for every three pages and gets 1.67 citations. Papers with more diagrams per page and, to a lesser extent, plots per page tended to be more influential (on average, a paper accrued two more citations for every extra diagram per page, and one more for every extra plot per page). By contrast, including photographs and equations seemed to decrease the chances of a paper being cited by others. That agrees with a study from 2012, whose authors counted (by hand) the number of mathematical expressions in over 600 biology papers and found that each additional equation per page reduced the number of citations a paper received by 22%. This does not mean that researchers should rush to include more diagrams in their next paper. Dr Howe has not shown what is behind the effect, which may merely be one of correlation, rather than causation. It could, for example, be that papers with lots of diagrams tend to be those that illustrate new concepts, and thus start a whole new field of inquiry. Such papers will certainly be cited a lot. On the other hand, the presence of equations really might reduce citations. Biologists (as are most of those who write and read the papers in PubMed Central) are notoriously mathsaverse. If that is the case, looking in a physics archive would probably produce a different result.

Abstract

Faceted classification is believed to be suitable for organizing digital information resources. Based on a faceted classification model suggested for Web resources (Zins, 2002), the current study analyzed popular Web directories from different Asian countries/areas and examined cultural differences reflected in their classification systems. Three popular Web directories from four countries/regions (China, Hong Kong, Korea, and Thailand) were selected and their classifications were analyzed and compared: a local Yahoo and two home-grown Web directories from each country/region. Based on the findings, the study suggests a model that might be more suitable to Asian culture.

Abstract

A draft of Functional Requirements for Authority Records (FRAR) was made available for worldwide review on IFLANET from July through October 2005. The FRANAR Working Group received comments from 12 individuals and 13 institutions (including 6 national libraries and 3 national-level cataloguing committees). The working group expresses its appreciation to all who took the time to prepare comments. The comments received were compiled into a comments log which totaled 145 pages. Seven members of the Working Group met at the Koninklijke Bibliothek, The Hague, Netherlands, on December 9, 2005, to consider these comments and to start revising the draft to reflect decisions made in response to the comments. The group was able to deal with about two-thirds of the comments during the meeting and, since the December meeting has had a series of four conference calls to complete discussions of the remaining comments, with additional calls anticipated before the Seoul meetings.

Abstract

Deals with library buildings, systems for arranging books (the impossibility of a strictly encylopedic scheme), library catalogues (recommends alphabetical catalogue), education of librarians, library administration, expansion and access, etc., with appendices on "Schrettinger 's library system," parchment manuscripts in the Royal Library in Copenhagen, and the recent history of this library. An interesting look at early ninteenth-century European library theory and practice (both that advocated by Molbech and that rejected by him).

Abstract

Bibliofile is a CD-ROM cataloguing product that provides LC MARC records. Available databases include English only, foreign language materials, audio-visual materials, as well as several that are more specialized. Bibliofile runs on a PC that may be connected to a network. Advantages over an online utility include lower cost, no telecommunication problems, no slow response times, fixed subscription rates with no hourly use charges, easy installation, searching and editing and good phone support. Disadvantages include no member-contributed records and no member holdings to use for interlibrary loan. A library should consider type and level of materials catalogued, existence of an interface with a local OPAC, total cataloguing time used, and other sources for ILL searching when considering bibliofile as a cataloguing alternative

Abstract

This paper focuses on meaning as the core concern and challenge of interoperability in a multilingual context. Korean subject headings, presently translated from English, crystallize issues attached to the semantics of translation in at least two languages (Korean, with written Chinese, and English). Presenting a model microcosm, which explains grammatical and semantic characteristics, and allows a search for equivalence of headings that have the closest approximation of semantic ranges, the study concludes the necessary conditions for linking multilingual subject headings and suggests an interoperable model for the transfer of meaning of headings across languages and cultures.

Abstract

Die Deutsche Bibliothek, the Library of Congress, and OCLC Online Computer Library Center are jointly developing a virtual international authority file (VIAF) for personal names which links authority records from the world's national bibliographic agencies and will be made freely available on the Web. The goals of the project are to prove the viability of automatically linking authority records from different national authority files and to demonstrate its benefits. The authority and bibliographic files from the Library of Congress and Die Deutsche Bibliothek were used to create the initial VIAF which contains over six million names with over a half million links. A key aspect of the project was the development of automated name matching algorithms which use information from both authority records and the corresponding bibliographic records. The practicality of algorithmically linking the personal names between national authority files was demonstrated; seventy percent of the authority records for personal names common to both files were automatically linked with an error rate of less than one percent. The long-term goal of the VIAF project is to combine the authoritative names from many national libraries and other significant sources into a shared global authority service.

Abstract

The purpose of this paper is to review the challenges confronting cataloguing as we have known it and to consider how these challenges might be confronted and whether they may be surmounted. The main focus of this paper is on cataloguing rather than the catalogue, although it is obviously difficult to separate one from the other. First of all, what does "cataloguing" mean? For the purposes of this paper I have adopted a broad definition incorporating the following activities: - description of the resource sufficient for purposes of identification and for differentiation from other similar resources - identification and control of access points - identification and control of relationships with other resources - subject analysis of the resource - assignment of subject indexing terms - assignment of classification numbers The challenges facing cataloguing are all too well known. In no particular order, the major challenges are: - Increasing inputs - New kinds of information resource - Competition from other mediation services. - Perception that cataloguing is high cost and offers poor value for money. - Fiscal constraints - Declining workforce This is a daunting list. We have a choice, we could, to paraphrase John Lennon, "Turn off our minds, relax and float down stream", until we retire, take voluntary redundancy, or retrain as marketing consultants; or, we can choose to confront these challenges and consider what they really mean for cataloguing.
