Articles Published and Downloaded by Public Health Scientists: Analysis of Data From the CDC Public Health Library, 2011-2013.

OBJECTIVE: To describe scientific information usage and publication patterns of the Centers for Disease Control and Prevention (CDC) Public Health Library and Information Center patrons. DESIGN: Administratively collected patron usage data and aggregate data on CDC-authored publications from the CDC Library for 3 consecutive years were analyzed. SETTING: The CDC Public Health Library and Information Center, which serves CDC employees nationally and internationally. PARTICIPANTS: Internal patrons and external users of the CDC Library. MAIN OUTCOME MEASURE(S): Three-year trends in full-text article publication and downloads including most common journals used for each purpose, systematic literature searches requested and completed, and subscriptions to a weekly public health current literature awareness service. RESULTS: From 2011 to 2013, CDC scientists published a total of 7718 articles in the peer-reviewed literature. During the same period, article downloads from the CDC Library increased 25% to more than 1.1 million, completed requests for reviews of the scientific literature increased by 34%, and electronic subscriptions to literature compilation services increased by 23%. CONCLUSIONS: CDC's scientific output and information use via the CDC Library are both increasing. Researchers and field staff are making greater use of literature review services and other customized information content delivery. Virtual public health library access is an increasingly important resource for the scientific practice of public health.

A preliminary analysis of library holdings as compared to the basic resources for pharmacy education list.

The catalogs of 11 university libraries were analyzed against the Basic Resources for Pharmaceutical Education (BRPE) to measure the percent coverage of the core total list as well as the core sublist. There is no clear trend in this data to link school age, size, or rank with percentage of coverage of the total list or the "First Purchase" core list when treated as independent variables. Approximately half of the schools have significantly higher percentages of core titles than statistically expected. Based on this data, it is difficult to predict what percentage of titles on the BRPE a library will contain.

Non-destructive assessment of parchment deterioration by optical methods.

A non-destructive and non-invasive method for quantitative characterization of parchment deterioration, based on spectral measurements, is proposed. Deterioration due to both natural aging (ancient parchments) and artificial aging (achieved by means of controlled UV irradiation and temperature treatment) was investigated. The effect of aging on parchment native fluorescence was correlated with its deterioration condition. Aging causes fluorescence intensity drop, spectral shift of the main peak, and an overall change in the fluorescence spectral features. Digital color imaging analysis based on visible reflectance from the parchment surface was also applied, and the correspondent color components (RGB) were successively correlated with the state of parchment deterioration/aging. The fluorescence and color imaging data were validated by analysis of historical parchments, aged between 50 and 2000 years and covering a large variety of states of deterioration. The samples were independently assessed by traditional microscopy methods. We conclude that the proposed optical method qualifies well as a non-destructive tool for rapid assessment of the stage of parchment deterioration.

Language and country preponderance trends in MEDLINE and its causes.

OBJECTIVE: The authors characterized the output of MEDLINE papers by language and country of publication during a thirty-four-year time period. METHODS: We classified MEDLINE's journal articles by country of publication (Anglos/Non-Anglos) and language (English/Non-English) for the years 1966 and from 1970 to 2000 at five-year intervals. Eight English-speaking countries were considered Anglos. Linear regression analysis of number of papers versus time was performed. RESULTS: The global number of papers increased linearly at a rate of 8,142 papers per year. Anglo and English papers also increased linearly (6,740 and 9,199, respectively). Journals of Non-Anglo countries accounted for 25% of the English language increase (2,438 per year). Only Non-English papers decreased at a rate of 1,056 fewer papers per year. These trends have led to overwhelming shares of English and Anglo papers in MEDLINE. In 2000, 68% of all papers were published in the 8 Anglo countries and 90% were written in English. CONCLUSIONS: The Anglo and English preponderances appear to be a consequence of at least two phenomena: (1) editorial policy changes in MEDLINE and in some journals from Non-Anglo countries and (2) factors affecting Non-Anglo researchers in the third world (publication constraints, migration, and undersupport). These are tentative conclusions that need confirmation.

Community outreach: from measuring the difference to making a difference with health information.

BACKGROUND: Community-based outreach seeks to move libraries beyond their traditional institutional boundaries to improve both access to and effectiveness of health information. The evaluation of such outreach needs to involve the community in assessing the program's process and outcomes. PURPOSE: Evaluation of community-based library outreach programs benefits from a participatory approach. To explain this premise of the paper, three components of evaluation theory are paired with relevant participatory strategies. CONCEPTS: The first component of evaluation theory is also a standard of program evaluation: use. Evaluation is intended to be useful for stakeholders to make decisions. A useful evaluation is credible, timely, and of adequate scope. Participatory approaches to increase use of evaluation findings include engaging end users early in planning the program itself and in deciding on the outcomes of the evaluation. A second component of evaluation theory seeks to understand what is being evaluated, such as specific aspects of outreach programs. A transparent understanding of the ways outreach achieves intended goals, its activities and linkages, and the context in which it operates precedes any attempt to measure it. Participatory approaches to evaluating outreach include having end users, such as health practitioners in other community-based organizations, identify what components of the outreach program are most important to their work. A third component of evaluation theory is concerned with the process by which value is placed on outreach. What will count as outreach success or failure? Who decides? Participatory approaches to valuing include assuring end-user representation in the formulation of evaluation questions and in the interpretation of evaluation results. CONCLUSIONS: The evaluation of community-based outreach is a complex process that is not made easier by a participatory approach. Nevertheless, a participatory approach is more likely to make the evaluation findings useful, ensure that program knowledge is shared, and make outreach valuing transparent.

"Smallball" evaluation: a prescription for studying community-based information interventions.

OBJECTIVES: This paper argues that focused evaluation studies of community-based informational interventions conducted over the life-cycle of the project ("smallball" studies) are more informative and useful than randomized experiments conducted only at the project's conclusion ("powerball" studies). METHOD: Based on two contrasting strategies in baseball, smallball and powerball studies are compared and contrasted, emphasizing how the distinctive features of community-based interventions lend advantage to smallball approaches. RESULTS: Smallball evaluations have several important advantages over powerball evaluations: before system development, they ensure that information resources address real community needs; during deployment, they ensure that the systems are suited to the capabilities of the users and to community constraints; and, after deployment, they enable as much as possible to be learned about the effects of the intervention in environments where randomized studies are usually impossible. IMPLICATIONS: Many in informatics see powerball studies as the only legitimate form of evaluation and so expect powerball studies to be done. These expectations should be revised in favor of smallball studies.

Effective e-learning for health professionals and students--barriers and their solutions. A systematic review of the literature--findings from the HeXL project.

INTRODUCTION: In 2003/4 the Information Management Research Institute, Northumbria University, conducted a research project to identify the barriers to e-learning for health professionals and students. The project also established possible ways to overcome these barriers. The North of England Workforce Development Confederation funded the project. METHODOLOGY: The project comprised a systematic review of the literature on barriers to and solutions/critical success factors for e-learning in the health field. Fifty-seven references were suitable for analysis. This review was supplemented by a questionnaire survey of learners and an interview study of learning providers to ensure that data identified from the literature were grounded in reality. RESULTS: The main barriers are: requirement for change; costs; poorly designed packages; inadequate technology; lack of skills; need for a component of face-to-face teaching; time intensive nature of e-learning; computer anxiety. A range of solutions can solve these barriers. The main solutions are: standardization; strategies; funding; integration of e-learning into the curriculum; blended teaching; user friendly packages; access to technology; skills training; support; employers paying e-learning costs; dedicated work time for e-learning. CONCLUSIONS: The authors argue that librarians can play an important role in e-learning: providing support and support materials; teaching information skills; managing and providing access to online information resources; producing their own e-learning packages; assisting in the development of other packages.

Collection analysis techniques used to evaluate a graduate-level toxicology collection.

Collections librarians from academic libraries are often asked, on short notice, to evaluate whether their collections are able to support changes in their institutions' curricula, such as new programs or courses or revisions to existing programs or courses. With insufficient time to perform an exhaustive critique of the collection and a need to prepare a report for faculty external to the library, a selection of reliable but brief qualitative and quantitative tests is needed. In this study, materials-centered and use-centered methods were chosen to evaluate the toxicology collection of the University of Saskatchewan (U of S) Library. Strengths and weaknesses of the techniques are reviewed, along with examples of their use in evaluating the toxicology collection. The monograph portion of the collection was evaluated using list checking, citation analysis, and classified profile methods. Cost-effectiveness and impact factor data were compiled to rank journals from the collection. Use-centered methods such as circulation and interlibrary loan data identified highly used items that should be added to the collection. Finally, although the data were insufficient to evaluate the toxicology electronic journals at the U of S, a brief discussion of three initiatives that aim to assist librarians as they evaluate the use of networked electronic resources in their collections is presented.
