Evidence-based librarianship: searching for the needed EBL evidence.

This paper discusses the challenges of finding evidence needed to implement Evidence-Based Librarianship (EBL). Focusing first on database coverage for three health sciences librarianship journals, the article examines the information contents of different databases. Strategies are needed to search for relevant evidence in the library literature via these databases, and the problems associated with searching the grey literature of librarianship. Database coverage, plausible search strategies, and the grey literature of library science all pose challenges to finding the needed research evidence for practicing EBL. Health sciences librarians need to ensure that systems are designed that can track and provide access to needed research evidence to support Evidence-Based Librarianship (EBL).

Evidence-based librarianship: an overview.

OBJECTIVE: To demonstrate how the core characteristics of both evidence-based medicine (EBM) and evidence-based health care (EBHC) can be adapted to health sciences librarianship. METHOD: Narrative review essay involving development of a conceptual framework. The author describes the central features of EBM and EBHC. Following each description of a central feature, the author then suggests ways that this feature applies to health sciences librarianship. RESULTS: First, the decision-making processes of EBM and EBHC are compatible with health sciences librarianship. Second, the EBM and EBHC values of favoring rigorously produced scientific evidence in decision making are congruent with the core values of librarianship. Third, the hierarchical levels of evidence can be applied to librarianship with some modifications. Library researchers currently favor descriptive-survey and case-study methods over systematic reviews, randomized controlled trials, or other higher levels of evidence. The library literature nevertheless contains diverse examples of randomized controlled trials, controlled-comparison studies, and cohort studies conducted by health sciences librarians. CONCLUSIONS: Health sciences librarians are confronted with making many practical decisions. Evidence-based librarianship offers a decision-making framework, which integrates the best available research evidence. By employing this framework and the higher levels of research evidence it promotes, health sciences librarians can lay the foundation for more collaborative and scientific endeavors.

The roles of library liaisons in a problem-based learning (PBL) medical school curriculum: a case study from University of New Mexico.

The relationships between problem-based learning (PBL) curricula and libraries have generated a substantial number of journal articles, but few have addressed the importance of the interaction between health science libraries and PBL curricula. This article attempts to contribute to this dimension through a description of the roles of library liaisons. First we describe the evolution of the liaison roles beginning 2 years prior to the implementation of a PBL curriculum. We then describe the core responsibilities of liaisons at the University of New Mexico (UNM) with mention of other innovative roles developed by some liaisons.

The vital few meet the trivial many: unexpected use patterns in a monographs collection.

PURPOSE: To test three related hypotheses about monographs circulation at academic health sciences libraries: (1) Juran's "Vital Few" Principle, sometimes incorrectly referred to as the "Pareto Principle"; (2) most (> 30%) new monographs will not circulate within four years; and, (3) Trueswell's 20/80 rule concerning intensity of monographs circulation. METHODS: Retrospective circulation study conducted at a major academic health sciences library in November 1997 on monographs acquired during 1993, utilizing an online review file. RESULTS: Unexpectedly, most monographs (84%) had circulated at least once in the four years following acquisition. Combining circulation and in-house data revealed that 90.7% of the monographs acquired in 1993 had been used at least once. Small percentages of these monographs produced disproportionately high circulation levels. CONCLUSION: Monographs circulation rates confirm Juran's Vital Few principle. Most monographs circulated at least once in contrast to results reported by the Pittsburgh Study or other studies reported by Hardesty and Fenske. The results do not comply with Trueswell's 20/80 ratio rule. Further research needs to investigate the effects of low students to books ratios and problem-based learning (PBL) curricula upon monographs utilization.

Identifying peer-reviewed journals in clinical medicine.

BACKGROUND: Two directories that contain information about serials also offer lists of thousands of journals identified as peer-reviewed. Librarians generally regard these lists as authoritative. OBJECTIVE: To identify clinical medicine journals on both peer-reviewed lists, measure the extent of discrepancies between these two lists, and determine the cause for these discrepancies. DESIGN: Comparison study. MEASUREMENTS: The extent of the discrepancies were tallied once the author had attempted to control for all extraneous variables. Interviews with the editorial staffs of each directory in regard to procedures for compiling the directories did not produce an explanation for these discrepancies. RESULTS: Nearly half (46%) of the 784 clinical medicine journals were unique to either one directory's list of peer-reviewed journals or the other's, indicating significant discrepancies between the two directories. Specifically, The Serials Directory listed 211 (27%) unique titles and Ulrich's International Periodicals Directory listed 150 (19%) unique titles (total unique titles = 46%). Both directories listed 423 of the same titles (54%). CONCLUSION: Widespread confusion about the actual identities of peer reviewed clinical medicine journals appears to explain the discrepancies between lists in these two periodical directories.

Accuracy of indexing coverage information as reported by serials sources.

This article reports on the accuracy of indexing service coverage information listed in three serials sources: Ulrich's International Periodicals Directory, SERLINE, and The Serials Directory. The titles studied were randomly selected journals that began publication in either 1981 or 1986. Aggregate results reveal that these serials sources perform at 92%, 97%, and 95% levels of accuracy respectively. When the results are analyzed by specific indexing services by year, the performance scores ranged from 80% to 100%. All three serials sources tend to underreport index coverage. The author advances five recommendations for improving index coverage accuracy and four specific proposals for future research. The results suggest that, for the immediate future, librarians should treat index coverage information reported in these three serials sources with some skepticism.

A problem-based learning curriculum in transition: the emerging role of the library.

This case study describes library education programs that serve the University of New Mexico School of Medicine, known for its innovative problem-based learning (PBL) curricular track. The paper outlines the specific library instruction techniques that are integrated into the curriculum. The adaptation of library instruction to a PBL mode of medical education, including the use of case studies, is discussed in detail. Also addressed are the planning processes for the new PBL curriculum scheduled for implementation in 1993, including the activities of library faculty and staff and the probable new role of the library in the new curriculum.
