    Abstract
    In this article recording evidence for data values in addition to the values themselves in bibliographic records and descriptive metadata is proposed, with the aim of improving the expressiveness and reliability of those records and metadata. Recorded evidence indicates why and how data values are recorded for elements. Recording the history of changes in data values is also proposed, with the aim of reinforcing recorded evidence. First, evidence that can be recorded is categorized into classes: identifiers of rules or tasks, action descriptions of them, and input and output data of them. Dates of recording values and evidence are an additional class. Then, the relative usefulness of evidence classes and also levels (i.e., the record, data element, or data value level) to which an individual evidence class is applied, is examined. Second, examples that can be viewed as recorded evidence in existing bibliographic records and current cataloging rules are shown. Third, some examples of bibliographic records and descriptive metadata with notes of evidence are demonstrated. Fourth, ways of using recorded evidence are addressed.

    Abstract
    Reports results of a study to examine interindexer consistency (the degree to which indexers, when assigning terms to a chosen record, will choose the same terms to reflect that record) in the PsycINFO database using 60 records that were inadvertently processed twice between 1996 and 1998. Five aspects of interindexer consistency were analysed. Two methods were used to calculate interindexer consistency: one posited by Hooper (1965) and the other by Rollin (1981). Aspects analysed were: checktag consistency (66.24% using Hooper's calculation and 77.17% using Rollin's); major-to-all term consistency (49.31% and 62.59% respectively); overall indexing consistency (49.02% and 63.32%); classification code consistency (44.17% and 45.00%); and major-to-major term consistency (43.24% and 56.09%). The average consistency across all categories was 50.4% using Hooper's method and 60.83% using Rollin's. Although comparison with previous studies is difficult due to methodological variations in the overall study of indexing consistency and the specific characteristics of the database, results generally support previous findings when trends and similar studies are analysed.

    Abstract
    ASSIA (Applied Social Science Index and Abtracts) started in 1987 as a bimonthly indexing and abstracting service in the society field, aimed at practitioners as well as sociologists. Considers the following aspects of the service: arrangement of ASSIA; journal coverage; indexing approach; services for subscribers; and who are the users?

    Abstract
    The LCC and DDC systems were devised and updated by librarians who had and have no access to the eventual frequency of use of each number in those classification systems. 80% of the monographs in a MARC file of over 1.000.000 records are classified into 20% of the classification numbers in the field of library science and only 20% of the mongraphs are classified into 80% of the classification numbers in the field of library science. Classification of monographs coulld be made easier and performed more accurately if many of the little used and unused numbers were eliminated and many of the most crowded numbers were expanded. A number of examples are included

    Abstract
    This study represents an attempt to compare indexing consistency between the catalogers of the National Library of Iran (NLI) on one side and 12 major academic and special libraries located in Tehran on the other. The research findings indicate that in 75% of the libraries the subject inconsistency values are 60% to 85%. In terms of subject classes, the consistency values are 10% to 35.2%, the mean of which is 22.5%. Moreover, the findings show that whenever the number of assigned terms increases, the probability of consistency decreases. This confirms Markey's findings in 1984.

    Footnote
    Rez. in JASIST 54(2003) no.4, S.356-357 (S.J. Lincicum): "Reliance upon shared cataloging in academic libraries in the United States has been driven largely by the need to reduce the expense of cataloging operations without muck regard for the Impact that this approach might have an the quality of the records included in local catalogs. In recent years, ever increasing pressures have prompted libraries to adopt practices such as "rapid" copy cataloging that purposely reduce the scrutiny applied to bibliographic records downloaded from shared databases, possibly increasing the number of errors that slip through unnoticed. Errors in bibliographic records can lead to serious problems for library catalog users. If the data contained in bibliographic records is inaccurate, users will have difficulty discovering and recognizing resources in a library's collection that are relevant to their needs. Thus, it has become increasingly important to understand the extent and nature of errors that occur in the records found in large shared bibliographic databases, such as OCLC WorldCat, to develop cataloging practices optimized for the shared cataloging environment. Although this monograph raises a few legitimate concerns about recent trends in cataloging practice, it fails to provide the "detailed look" at misinformation in library catalogs arising from linguistic errors and mistakes in subject analysis promised by the publisher. A basic premise advanced throughout the text is that a certain amount of linguistic and subject knowledge is required to catalog library materials effectively. The author emphasizes repeatedly that most catalogers today are asked to catalog an increasingly diverse array of materials, and that they are often required to work in languages or subject areas of which they have little or no knowledge. He argues that the records contributed to shared databases are increasingly being created by catalogers with inadequate linguistic or subject expertise. This adversely affects the quality of individual library catalogs because errors often go uncorrected as records are downloaded from shared databases to local catalogs by copy catalogers who possess even less knowledge. Calling misinformation an "evil phenomenon," Bade states that his main goal is to discuss, "two fundamental types of misinformation found in bibliographic and authority records in library catalogs: that arising from linguistic errors, and that caused by errors in subject analysis, including missing or wrong subject headings" (p. 2). After a superficial discussion of "other" types of errors that can occur in bibliographic records, such as typographical errors and errors in the application of descriptive cataloging rules, Bade begins his discussion of linguistic errors. He asserts that sharing bibliographic records created by catalogers with inadequate linguistic or subject knowledge has, "disastrous effects an the library community" (p. 6). To support this bold assertion, Bade provides as evidence little more than a laundry list of errors that he has personally observed in bibliographic records over the years. When he eventually cites several studies that have addressed the availability and quality of records available for materials in languages other than English, he fails to describe the findings of these studies in any detail, let alone relate the findings to his own observations in a meaningful way. Bade claims that a lack of linguistic expertise among catalogers is the "primary source for linguistic misinformation in our databases" (p. 10), but he neither cites substantive data from existing studies nor provides any new data regarding the overall level of linguistic knowledge among catalogers to support this claim. The section concludes with a brief list of eight sensible, if unoriginal, suggestions for coping with the challenge of cataloging materials in unfamiliar languages.
    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.
    Arguing that catalogers need to work both quickly and accurately, Bade maintains that employing specialists is the most efficient and effective way to achieve this outcome. Far less compelling than these arguments are Bade's concluding remarks, in which he offers meager suggestions for correcting the problems as he sees them. Overall, this essay is little more than a curmudgeon's diatribe. Addressed primarily to catalogers and library administrators, the analysis presented is too superficial to assist practicing catalogers or cataloging managers in developing solutions to any systemic problems in current cataloging practice, and it presents too little evidence of pervasive problems to convince budget-conscious library administrators of a need to alter practice or to increase their investment in local cataloging operations. Indeed, the reliance upon anecdotal evidence and the apparent nit-picking that dominate the essay might tend to reinforce a negative image of catalogers in the minds of some. To his credit, Bade does provide an important reminder that it is the intellectual contributions made by thousands of erudite catalogers that have made shared cataloging a successful strategy for improving cataloging efficiency. This is an important point that often seems to be forgotten in academic libraries when focus centers an cutting costs. Had Bade focused more narrowly upon the issue of deintellectualization of cataloging and written a carefully structured essay to advance this argument, this essay might have been much more effective." - KO 29(2002) nos.3/4, S.236-237 (A.

    Abstract
    The 'KeyWords Plus' in the Science Citation Index database represents an approach to combining citation and semantic indexing in describing the document content. This paper explores the similariites or dissimilarities between citation-semantic and analytic indexing. The dataset consisted of over 400 matching records in the SCI and MEDLINE databases on antibiotic resistance in pneumonia. The degree of similarity in indexing terms was found to vary on a scale from completely different to completely identical with various levels in between. The within-document similarity in the 2 databases was measured by a variation on the Jaccard coefficient - the Inclusion Index. The average inclusion coefficient was 0,4134 for SCI and 0,3371 for Medline. The 20 terms occuring most frequently in each database were identified. The 2 groups of terms shared the same terms that consist of the 'intellectual base' for the subject. conceptual similarity was analyzed through scatterplots of matching and nonmatching terms vs. partially identical and broader/narrower terms. The study also found that both databases differed in assigning terms in various semantic categories. Implications of this research and further studies are suggested

    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
    Studies the quality of subject indexing by Chemical Abstracts Indexing Service by confronting authors with the particular indexing terms attributed to their computer, for 270 articles published in 54 journals, 5 articles out of each journal. Responses (80%) indicate the superior quality of keywords, both as content descriptors and as retrieval tools. Author judgements on these 2 different aspects do not always converge, however. CAS's indexing policy to cover only 'new' aspects is reflected in author's judgements that index lists are somewhat incomplete, in particular in the case of thesaurus terms (index headings). The large effort expanded by CAS in maintaining and using a subject thesuaurs, in order to select valid index headings, as compared to quick and cheap keyword postings, does not lead to clear superior quality of thesaurus terms for document description nor in retrieval. Some 20% of papers were not placed in 'proper' CA main section, according to authors. As concerns the use of indexing data by third parties, in bibliometrics, users should be aware of the indexing policies behind the data, in order to prevent invalid interpretations

    Abstract
    The depth of indexing, the number of terms assigned on average to each document in a retrieval system as entry points, has a significantly effect on the standard retrieval performance measures in modern commercial retrieval systems, just as it did in previous experimental work. Tests on the effect of basic index search, as opposed to controlled vocabulary search, in these real systems are quite different than traditional comparisons of free text searching with controlled vocabulary searching. In modern commercial systems the controlled vocabulary serves as a precision device, since the strucure of the default for unqualified search terms in these systems requires that it do so.

    Abstract
    A known-item search for abstracts to previously retrieved references revealed that 2 documents from the same annual volume had been indexed twice. Working from the premise that the whole volume may have been double-indexed, a search strategy was devised that limited the journal code to the year in question. 57 references were retrieved, comprising 28 pairs of duplicates plus a citation for the whole volume. Author, title, source and descriptors were requested off-line and the citations were paired with their duplicates. The 4 categories of descriptors-major descriptors, minor descriptors, subheadings and check-tags-were compared for depth and consistency of indexing and lessons that might be learnt from the study are discussed.

    Abstract
    Subject indexing plays an important role in supporting subject access to information resources. Current subject indexing systems do not make adequate distinctions on the importance of assigned subject descriptors. Assigning numeric weights to subject descriptors to distinguish their importance to the documents can strengthen the role of subject metadata. Automated methods are more cost-effective. This study compares different automated weighting methods in different environments. Two evaluation methods were used to assess the performance. Experiments on three datasets in the biomedical domain suggest the performance of different weighting methods depends on whether it is an abstract or full text environment. Mutual information with bag-of-words representation shows the best average performance in the full text environment, while cosine with bag-of-words representation is the best in an abstract environment. The cosine measure has relatively consistent and robust performance. A direct weighting method, IDF (Inverse Document Frequency), can produce quick and reasonable estimates of the weights. Bag-of-words representation generally outperforms the concept-based representation. Further improvement in performance can be obtained by using the learning-to-rank method to integrate different weighting methods. This study follows up Lu and Mao (Journal of the Association for Information Science and Technology, 66, 1776-1784, 2015), in which an automated weighted subject indexing method was proposed and validated. The findings from this study contribute to more effective weighted subject indexing.

    Abstract
    The literature on assigned indexing considers three possible viewpoints-the author's viewpoint as evidenced in the title, the users' viewpoint, and the indexer's viewpoint-and asks whether and which of those views should be reflected in an indexer's choice of terms to assign to an item. We study this question empirically, as opposed to normatively. Based on the literature that discusses whose viewpoints should be reflected, we construct a research model that includes those same three viewpoints as factors that might be influencing term assignment in actual practice. In the unique study design that we employ, the records of term assignments made by identified indexers in academic libraries are cross-referenced with the results of a survey that those same indexers completed on political views. Our results indicate that in our setting, variance in term assignment was best explained by indexers' personal political views.

    Abstract
    Our purpose is to adapt a statistical method for the analysis of discrete numerical series to the keywords appearing in scientific articles of a given area. As an example, we apply our methodological approach to the study of the keywords in the Library and Information Sciences (LIS) area. Our objective is to detect the new author keywords that appear in a fixed knowledge area in the period of 1 year in order to quantify the probabilities of survival for 10 years as a function of the impact of the journals where they appeared. Many of the new keywords appearing in the LIS field are ephemeral. Actually, more than half are never used again. In general, the terms most commonly used in the LIS area come from other areas. The average survival time of these keywords is approximately 3 years, being slightly higher in the case of words that were published in journals classified in the second quartile of the area. We believe that measuring the appearance and disappearance of terms will allow understanding some relevant aspects of the evolution of a discipline, providing in this way a new bibliometric approach.

    Abstract
    This study examined Library of Congress Classification (LCC)-based class numbers assigned to a representative sample of 200 titles in 52 American library systems to determine the level of consistency within and across those systems. The results showed that under the condition that a library system has a title, the probability of that title having the same LCC-based class number across library systems is greater than 85 percent. An examination of 121 titles displaying variations in class numbers among library systems showed certain titles (for example, multi-foci titles, titles in series, bibliographies, and fiction) lend themselves to alternate class numbers. Others were assigned variant numbers either due to latitude in the schedules or for reasons that cannot be pinpointed. With increasing dependence on copy cataloging, the size of such variations may continue to decrease. As the preferred class number with its alternates represents a title more fully than just the preferred class number, this paper argues for continued use of alternates by library systems and for finding a method to link alternate class numbers to preferred class numbers for enriched subject access through local and union catalogs.

    Abstract
    Indexing consistency between Library of Congress and British Library catalogers using the LCSH is compared.82 titles published in 1987 in the field of library and information science were identified for comparison, and for each title its LC subject headings, assigned by both LC and BL catalogers, were compared. By applying Hooper's 'consistency of a pair' equation, the average indexing consistency value was calculated for the 82 titles. The average indexing value between LC and BL catalogers is 16% for exact matches, and 36% for partial matches

    Abstract
    Presents results of an experiment in which 8 indexers (4 beginners and 4 experts) were asked to index the same 4 documents with 2 different thesauri. The 3 kind of verbal reports provide complementary data on strategic behaviour. it is of prime importance to consider the indexing task as an ill-defined problem, where the solutionm is partly defined by the indexer
