    Abstract
    The paper discusses the consistency of fiction indexing of library professionals and patrons based on an empirical test. Indexing was carried out with a Finnish fictional thesaurus and all of the test persons indexed the same five novels. The consistency of indexing was determined to be low; several reasons are postulated. Also an algorithm for typified indexing of fiction is given as well as some suggestions for the development of fiction information retrieval systems and content representation.

    Abstract
    Wolfram and Zhang are interested in the effect of different indexing exhaustivity, by which they mean the number of terms chosen, and of different index term distributions and different term weighting methods on the resulting document cluster organization. The Distance Angle Retrieval Environment, DARE, which provides a two dimensional display of retrieved documents was used to represent the document clusters based upon a document's distance from the searcher's main interest, and on the angle formed by the document, a point representing a minor interest, and the point representing the main interest. If the centroid and the origin of the document space are assigned as major and minor points the average distance between documents and the centroid can be measured providing an indication of cluster organization. in the form of a size normalized similarity measure. Using 500 records from NTIS and nine models created by intersecting low, observed, and high exhaustivity levels (based upon a negative binomial distribution) with shallow, observed, and steep term distributions (based upon a Zipf distribution) simulation runs were preformed using inverse document frequency, inter-document term frequency, and inverse document frequency based upon both inter and intra-document frequencies. Low exhaustivity and shallow distributions result in a more dense document space and less effective retrieval. High exhaustivity and steeper distributions result in a more diffuse space.

    Footnote
    Bade begins his discussion of errors in subject analysis by summarizing the contents of seven records containing what he considers to be egregious errors. The examples were drawn only from items that he has encountered in the course of his work. Five of the seven records were full-level ("I" level) records for Eastern European materials created between 1996 and 2000 in the OCLC WorldCat database. The final two examples were taken from records created by Bade himself over an unspecified period of time. Although he is to be commended for examining the actual items cataloged and for examining mostly items that he claims to have adequate linguistic and subject expertise to evaluate reliably, Bade's methodology has major flaws. First and foremost, the number of examples provided is completely inadequate to draw any conclusions about the extent of the problem. Although an in-depth qualitative analysis of a small number of records might have yielded some valuable insight into factors that contribute to errors in subject analysis, Bade provides no Information about the circumstances under which the live OCLC records he critiques were created. Instead, he offers simplistic explanations for the errors based solely an his own assumptions. He supplements his analysis of examples with an extremely brief survey of other studies regarding errors in subject analysis, which consists primarily of criticism of work done by Sheila Intner. In the end, it is impossible to draw any reliable conclusions about the nature or extent of errors in subject analysis found in records in shared bibliographic databases based an Bade's analysis. In the final third of the essay, Bade finally reveals his true concern: the deintellectualization of cataloging. It would strengthen the essay tremendously to present this as the primary premise from the very beginning, as this section offers glimpses of a compelling argument. Bade laments, "Many librarians simply do not sec cataloging as an intellectual activity requiring an educated mind" (p. 20). Commenting an recent trends in copy cataloging practice, he declares, "The disaster of our time is that this work is being done more and more by people who can neither evaluate nor correct imported errors and offen are forbidden from even thinking about it" (p. 26). Bade argues that the most valuable content found in catalog records is the intellectual content contributed by knowledgeable catalogers, and he asserts that to perform intellectually demanding tasks such as subject analysis reliably and effectively, catalogers must have the linguistic and subject knowledge required to gain at least a rudimentary understanding of the materials that they describe. He contends that requiring catalogers to quickly dispense with materials in unfamiliar languages and subjects clearly undermines their ability to perform the intellectual work of cataloging and leads to an increasing number of errors in the bibliographic records contributed to shared databases.

    Abstract
    In this article, the authors analyze the keywords given by authors of scientific articles and the descriptors assigned to the articles to ascertain the presence of the keywords in the descriptors. Six-hundred forty INSPEC (Information Service for Physics, Engineering, and Computing), CAB (Current Agriculture Bibliography) abstracts, ISTA (Information Science and Technology Abstracts), and LISA (Library and Information Science Abstracts) database records were consulted. After detailed comparisons, it was found that keywords provided by authors have an important presence in the database descriptors studied; nearly 25% of all the keywords appeared in exactly the same form as descriptors, with another 21% though normalized, still detected in the descriptors. This means that almost 46% of keywords appear in the descriptors, either as such or after normalization. Elsewhere, three distinct indexing policies appear, one represented by INSPEC and LISA (indexers seem to have freedom to assign the descriptors they deem necessary); another is represented by CAB (no record has fewer than four descriptors and, in general, a large number of descriptors is employed). In contrast, in ISTA, a certain institutional code exists towards economy in indexing because 84% of records contain only four descriptors.

    Abstract
    Purpose - The purpose of this article is to examine interindexer consistency on a larger scale than other studies have done to determine if group consensus is reached by larger numbers of indexers and what, if any, relationships emerge between assigned terms. Design/methodology/approach - In total, 64 MLIS students were recruited to assign up to five terms to a document. The authors applied basic data modeling and the exploratory statistical techniques of multi-dimensional scaling (MDS) and hierarchical cluster analysis to determine whether relationships exist in indexing consistency and the coocurrence of assigned terms. Findings - Consistency in the assignment of indexing terms to a document follows an inverse shape, although it is not strictly power law-based unlike many other social phenomena. The exploratory techniques revealed that groups of terms clustered together. The resulting term cooccurrence relationships were largely syntagmatic. Research limitations/implications - The results are based on the indexing of one article by non-expert indexers and are, thus, not generalizable. Based on the study findings, along with the growing popularity of folksonomies and the apparent authority of communally developed information resources, communally developed indexes based on group consensus may have merit. Originality/value - Consistency in the assignment of indexing terms has been studied primarily on a small scale. Few studies have examined indexing on a larger scale with more than a handful of indexers. Recognition of the differences in indexing assignment has implications for the development of public information systems, especially those that do not use a controlled vocabulary and those tagged by end-users. In such cases, multiple access points that accommodate the different ways that users interpret content are needed so that searchers may be guided to relevant content despite using different terminology.
