The Changing Nature of the Catalog and its Integration with Other Discovery Tools: Draft 2B

Objectives: The study sought to investigate how Spanish names are handled by national and international databases and to identify mistakes that can undermine the usefulness of these databases for locating and retrieving works by Spanish authors.

Methods: The authors sampled 172 articles published by authors from the University of Granada Medical School between 1987 and 1996 and analyzed the variations in how each of their names was indexed in Science Citation Index (SCI), MEDLINE, and Indice Medico Espanol (IME). The number and types of variants that appeared for each author's name were recorded and compared across databases to identify inconsistencies in indexing practices. We analyzed the relationship between variability (number of variants of an author's name) and productivity (number of items the name was associated with as an author), the consequences for retrieval of information, and the most frequent indexing structures used for Spanish names.

Results: The proportion of authors who appeared under more then one name was 48.1% in SCI, 50.7% in MEDLINE, and 69.0% in IME. Productivity correlated directly with variability: more than 50% of the authors listed on five to ten items appeared under more than one name in any given database, and close to 100% of the authors listed on more than ten items appeared under two or more variants. Productivity correlated inversely with retrievability: as the number of variants for a name increased, the number of items retrieved under each variant decreased. For the most highly productive authors, the number of items retrieved under each variant tended toward one. The most frequent indexing methods varied between databases. In MEDLINE and IME, names were indexed correctly as “first surname second surname, first name initial middle name initial” (if present) in 41.7% and 49.5% of the records, respectively. However, in SCI, the most frequent method was “first surname, first name initial second name initial” (48.0% of the records) and first surname and second surname run together, first name initial (18.3%).

Conclusions: Retrievability on the basis of author's name was poor in all three databases. Each database uses accurate indexing methods, but these methods fail to result in consistency or coherence for specific entries. The likely causes of inconsistency are: (1) use by authors of variants of their names during their publication careers, (2) lack of authority control in all three databases, (3) the use of an inappropriate indexing method for Spanish names in SCI, (4) authors' inconsistent behaviors, and (5) possible editorial interventions by some journals. We offer some suggestions as to how to avert the proliferation of author name variants in the databases.

Spanish personal name variations in national and international biomedical databases: implications for information retrieval and bibliometric studies.

Functional Requirements for Bibliographic Records (FRBR), is the title of a report prepared by an IFLA study group and published in 1998. The term “FRBR” is used to refer both to the report and to the conceptual model described in that report. The FRBR report defined the user tasks find, identify, select, and obtain; developed the FRBR conceptual model to describe bibliographic data; and mapped the user tasks to the bibliographic data. The FRBR model is based on entity-relationship modeling and identifies three groups of entities. Group 1, consisting of work, expression, manifestation, and item is the most fully developed. Group 2 consists of persons and corporate bodies. Group 3 consists of entities that can serve as subjects but that belong to neither Group 1 nor Group 2. The FRBR model has generated both theoretical discussion and applied research, and has affected the modeling of authority data, the development of cataloging rules, and the design of systems for the display of bibliographic data. Although there are unresolved issues associated with the FRBR model it still provides hope for a useful organization of the bibliographic universe

Functional Requirements for Bibliographic Records (FRBR)

Shoulder complaints, and especially the outlet-impingement syndrome, are a common condition. Among other things, poor posture has been discussed as a cause. A correlation between impingement syndrome and restricted mobility of the thoracic spine (T) has been described earlier, but there has been no motion analysis of the thoracic spine to show these correlations. In the present prospective study, we intended to find out whether there is a significant difference in the thoracic sagittal range of motion (ROM) between patients with a shoulder outlet impingement syndrome and a group of patients who had no shoulder pathology. Secondly, we wanted to clarify whether Ott's sign correlates with ultrasound topometric measurements. Two sex- and age-matched groups (2 × n = 39) underwent a clinical and an ultrasound topometric examination. The postures examined were sitting up straight, sitting in maximal flexion and sitting in maximal extension. The disabilities of the arm, shoulder and hand (DASH) score (obtained by means of a self-assessment questionnaire) and the Constant score were calculated. Lengthening and shortening of the dorsal projections of the spine in functional positions was measured by tape with Ott's sign. On examination of the thoracic kyphosis in the erect seated posture there were no significant differences between the two groups (p = 0.66). With ultrasound topometric measurement it was possible to show a significantly restricted segmental mobility of the thoracic spine in the study group compared with the control group (p = 0.01). An in-depth look at the mobility of the subsegments T1-4, T5-8 and T9-12 revealed that differences between the groups in the mobility in the lower two sections of the thoracic spine were significant (T5-8: p = 0.03; T9-12: p = 0.02). The study group had an average Constant score of 35.1 points and the control group, 85.5 (p < 0.001). On the DASH score the patient group reached 34.2 points and the control group, 1.4 (p < 0.001). The results of Ott's sign differed significantly between the two collectives (p = 0.0018), but showed a weak correlation with the ultrasound topometric measurements (study group flexion/extension: r = 0.36/0.43, control group flexion/extension: r = 0.29/0.26). The mobility of the thoracic spine should receive more attention in the diagnosis and therapy of patients with shoulder outlet impingement syndrome.

A palpation reference line coursing between the superior-most aspect of the iliac crests has been reported to cross the L4 spinous process or L4/L5 intervertebral space in approximately 80% of the population. Comparable data have not been defined for the line coursing between the posterior superior iliac spines (PSIS). The purpose of this study was to compare the anatomical consistency of the PSIS to the iliac crest as landmarks used for spinal palpation. One hundred computerized tomographic images were reviewed in a three-dimensional setting. Two horizontal lines were constructed on each image: Line 1 representing the superior-most aspect of the iliac crest and Line 2 representing the inferior margin of the PSIS. The vertical distance between each horizontal line and the inferior edge of its respective spinous process were measured. The PSIS corresponded to the S2 spinous process in 81% of subjects and the iliac crest to the L4 spinous process in 59% of subjects. Distance measures suggest that the PSIS was closer to S2 versus the iliac crest to L4 (t = 6.998; P < 0.01). The PSIS crossed S2 more frequently than the iliac crest crossed L4 (chi(2) = 12.719, P < or = 0.01). The study findings support the relationship between the PSIS, and the spinous process of S2 is more consistent when compared to the iliac crest and the spinous process of L4. The PSIS reference line may be used to find S2 as a reference standard in validity and reliability palpation studies in the lower lumbar spine.

The promulgation of the entity-analysis model set forth in Functional Requirements for Bibliographic Records (FRBR) has led to its experimental application to a variety of collections of existing bibliographic records. Records for continuing resources (CR) have been deliberately excluded from these applications due to perceived difficulties in applying the model. These difficulties derive from a variety of sources: the imprecision of the more abstract FRBR Group 1 entities (work and expression), divergent definitions of two concepts central to bibliographic records—the work and authorship—when applied to continuing resources, and the relative merits of various mechanisms (e.g., main entries, MARC 21 linking entry fields) available for collocating records for CR. Additionally, because a particular library may own a single CR work as a sequence (overlapping or otherwise) of partially complete manifestations, the Group 1 hierarchy of the FRBR model tends to be inefficient for presenting these holdings to the user in a concise manner.

The FRBR Model As Applied to Continuing Resources

Random samples of main entries on monograph catalog records created by the Library of Congress and the British Library were compared for the year 1989 in order to examine one aspect of the potential usefulness to the Library of Congress of British Library monograph cataloging, especially regarding the extent of agreement in cataloging practice between the two national bibliographic agencies. It was estimated that between 27.1% and 31.5% of the monograph entries in the printed 1989 annual cumulation of the British National Bibliography had been cataloged by both the British Library and the Library of Congress. It was further estimated that, for both choice and form of main entry, agreement was achieved between 60% and 70% of the time, and for choice of main entry alone, between 96% and 99% of the time

Summary Resource Description and Access(RDA) is scheduled to replace the AACR2 cataloging code in 2008. This presentation provided an overview of RDA, especially as it relates to serials. Among the topics explored were RDA's background, organization, and relationship to various standards (including FRBR, the draft Statement on International Cataloging Principles, and MARC 21). In addition, the presentation discussed the potential impact of the new code on current cataloging practices.

The shape of things to come : Resource description and access (RDA)

The Joint Steering Committee for Development of Resource Description and Access (RDA) has invited the German National Library to prepare a discussion paper on how RDA might accommodate bibliographic descriptions of serials based on the latest available issue. Such descriptions in RDA are currently based on the earliest available issue. Three possible implementation scenarios for accommodation of such descriptions in RDA are examined: (1) an “optimal” implementation in which a single record could be used to generate descriptions and access points based on either approach; (2) an “intermediate” implementation in which records created in a system employing one approach could be used to generate access points based on either approach and so exchanged with a system employing the other approach; and (3) a “minimal” implementation in which RDA would support either approach, but records could not be easily exchanged with a system employing the other approach.
