1.  Towards the bibliography of life 
ZooKeys  2011;151-166.
This paper discusses how we intend to take forward the vision of a Bibliography of Life in the ViBRANT project. The underlying principle of the Bibliography is to provide taxonomists and others with a freely accessible bibliography covering the whole of life. Such a bibliography has been achieved for specific study areas within taxonomy, but not for “life” as a whole.
The creation of such a comprehensive tool has been hindered by various social and technical issues. The social concerns focus on the willingness of users to contribute to the Bibliography. The technical concerns relate to the architecture required to deliver the Bibliography. These issues are discussed in the paper and approaches to addressing them within the ViBRANT project are described, to demonstrate how we can now seriously consider building a Bibliography of Life. We are particularly interested in the potential of the resulting tool to improve the quality of bibliographic references. Through analysing the large number of references in the Bibliography we will be able to add metadata by resolving known issues such as geographical name variations. This should result in a tool that will assist taxonomists in two ways. Firstly, it will be easier for them to discover relevant literature, especially pre-digital literature; and secondly, it will be easier for them to identify the canonical form for a citation
The paper also covers related issues relevant to building the tool in ViBRANT, including implementation and copyright, with suggestions as to how we could address them.

2.  Finding European bioethical literature: an evaluation of the leading abstracting and indexing services 
Journal of Medical Ethics  2004;30(3):299-303.
Objectives: In this study the author aimed to provide information for researchers to help them with the selection of suitable databases for finding medical ethics literature. The quantity of medical ethical literature that is indexed in different existing electronic bibliographies was ascertained.
Method: Using the international journal index Ulrich's Periodicals Directory, journals on medical ethics were identified. The electronic bibliographies indexing these journals were analysed. In an additional analysis documentalists indexing bioethical literature were asked to name European journals on medical ethics. The bibliographies indexing these journals were examined.
Results: Of 290 journals on medical ethics 173 were indexed in at least one bibliography. Current Contents showed the highest coverage with 66 (22.8%) journals indexed followed by MEDLINE (22.1%). By a combined search in the top ten bibliographies with the highest coverage, a maximum coverage of 45.2% of all journals could be reached. All the bibliographies showed a tendency to index more North American than European literature. This result was verified by the supplementary analysis of a sample of continental European journals. Here EMBASE covered the highest number of journals (20.6%) followed by the Russian Academy of Sciences Bibliographies (19.2%).
Conclusion: A medical ethics literature search has to be carried out in several databases in order to reach an adequate collection of literature. The databases one wishes to combine should be carefully chosen. There seems to be a regional bias in the most popular databases, favouring North American periodicals compared with European literature on medical ethics.

3.  Updating a bibliography using the related articles function within PubMed. 
Comprehensive bibliographies are useful for conducting reviews of the literature, and for assessing the progress within a field. These bibliographies may be broad and inclusive, or focused and precise in their inclusion criteria. In either case, the task of maintaining a complete bibliography within a particular area of research is made difficult by the diversity, complexity and huge volume of newly published literature. In an effort to effectively and automatically retrieve relevant literature, different search strategies and indexing tools have been developed, including the RELATED ARTICLES function provided with the PubMed system. In this paper, we report a program for incremental updates of a bibliography using the PubMed RELATED ARTICLES function. Given a highly specialized starting bibliography of experimental measurements of the structure of the 30S bacterial ribosomal subunit, the system was applied to find additional relevant references. For this particular task, the system has a recall of 75%, a strict precision of 32% and a partial precision of 42%. Our results are notable because although the RELATED ARTICLES function is purely statistical, it is nonetheless able to select a very narrowly defined set of articles from the literature. We discuss the tradeoffs between having a user to evaluate many articles of possible interest in a single session, versus asking a user to evaluate a small set of articles on a periodic basis.

4.  FlyBase: improvements to the bibliography 
Nucleic Acids Research  2012;41(D1):D751-D757.
An accurate, comprehensive, non-redundant and up-to-date bibliography is a crucial component of any Model Organism Database (MOD). Principally, the bibliography provides a set of references that are specific to the field served by the MOD. Moreover, it serves as a backbone to which all curated biological data can be attributed. Here, we describe the organization and main features of the bibliography in FlyBase (flybase.org), the MOD for Drosophila melanogaster. We present an overview of the current content of the bibliography, the pipeline for identifying and adding new references, the presentation of data within Reference Reports and effective methods for searching and retrieving bibliographic data. We highlight recent improvements in these areas and describe the advantages of using the FlyBase bibliography over alternative literature resources. Although this article is focused on bibliographic data, many of the features and tools described are applicable to browsing and querying other datasets in FlyBase.

5.  The Recurring Bibliographies Program of MEDLARS * 
Recurring bibliographies are by-products of the MEDLARS system which are prepared by the National Library of Medicine in collaboration with nonprofit scientific and professional societies and institutions and government agencies that represent a specialty area of biomedical research or practice. The sponsor generally assumes responsibility for the costs of publication and distribution. At present MEDLARS has a planned capacity of fifty such recurring bibliographies. The subject parameters and format are defined by the representatives of the sponsoring organization and the NLM Search, MeSH, and Index staffs. As citations are regularly put into the MEDLARS store, each one that qualifies for a recurring bibliography is identified and tagged by the computer with the number assigned to the pertinent RB. The MEDLARS store is searched for citations for a particular recurring bibliography according to the schedule specified by the sponsoring organization, and the output is printed from a GRACE tape.

6.  Bibliography of Bioethics and Index Medicus: comparison of coverage, publication delay, and ease of recall for journal articles on bioethics. 
Citations selected from the bibliographies of recent texts, a specialized subject bibliography, and review articles were checked in both Cumulated Index Medicus (IM) and the Bibliography of Bioethics (BB) to compare coverage, publication delay, probable causes of indexing and retrieval failure, and the ease with which relevant citations were retrieved. The study also attempted to determine whether BB included appropriate articles from the MEDLINE database in a timely and systematic manner. While 98% of the IM citations appeared within a year of publication, 79% of the BB citations appeared two to three years after their publication dates. The average citation appeared twice as frequently in IM as in BB.

8.  Whiplash: a selective annotated bibliography 
Objective:
To review the literature on whiplash injury including an overview, collision mechanics, pathophysiology, neurobehavioral, imaging, treatment/management, prognosis, outcomes, and litigation.
Design:
An annotated bibliography.
Methods:
A literature search of MEDLINE from 1987 to 1995 and CHIROLARS from 1900 to 1996, with emphasis on the last ten years, was performed. Conference proceedings and the personal files of the authors were searched for relevant citations. Key words utilized in the search were whiplash injury, acceleration/deceleration injury, neck pain, head pain, cognitive impairment, treatment, imaging, prognosis and litigation.
Results:
This annotated bibliography identifies key studies and potential models for future research.
Conclusions:
There is currently a lack of clinical consensus both in practice and in the literature regarding the evaluation and management of an episode of whiplash injury. This annotated bibliography has been developed in an attempt to provide an overview of the literature regarding various issues surrounding an episode of whiplash injury.

9.  Health aspects of Arctic exploration – Alaska’s medical history based on the research files of Dr. Robert Fortuine 
International Journal of Circumpolar Health  2013;72:10.3402/ijch.v72i0.21264.
Background
Robert Fortuine provided basic medical care to Alaska Native people, chronicled the Health Aspects of Arctic Exploration and through a number of influential publications, was the first to thoroughly document and analyse Alaska’s Medical History. This overview of his published work will provide the reader with a detailed overview, so that they can begin to explore Dr. Fortuine’s many published works in more detail.
Objective
This review will explore Alaska’s Medical History and the Health Aspects of Arctic Exploration through the research files and the 10 most significant publications of Dr. Robert Fortuine.
Design
Review of Dr. Fortuine’s major works and the master bibliography has over 3,000 references and 81 subjects. The master bibliography is a merger of 55 separate bibliographies, which provides a wealth of bibliographic information. This paper will describe his 10 most significant publications, 2 of which began as a journal issue.
Results
Dr. Fortuine was a prolific writer throughout his career, publishing 134 articles and books. He wrote papers and books on Alaska’s medical history, tuberculosis and health care delivery from Russian–America through the Public Health Service efforts in the territory and then the State of Alaska. The master bibliography has over 3,000 references and 81 subjects. This list has a significant number of entries for tuberculosis with almost one-third of the entries including this heading. Others dwell on the history of “pre-contact” health, the history of Alaska Native health care, the history of the Alaska Department of Health, especially the tuberculosis programme, the role of the US Public Health Service and traditional medicine. He completely reviewed every Governors’ and the US Surgeon General’s reports in regard to Alaska content. This paper describes his 10 most significant publications.
Conclusions
Robert Fortuine’s published works offer a wealth of information and insight into Alaska’s Medical History and the Health Aspects of Arctic Exploration. As is probably true for many historians, he began small, creating a bibliography and adapting a talk before tackling his first full-length book. Readers who sample his many works will be enriched and enlightened.

10.  Contact dermatitis and other skin conditions in instrumental musicians 
BMC Dermatology  2004;4:3.
Background
The skin is important in the positioning and playing of a musical instrument. During practicing and performing there is a permanent more or less intense contact between the instrument and the musician's skin. Apart from aggravation of predisposed skin diseases (e.g., atopic eczema or psoriasis) due to music-making, specific dermatologic conditions may develop that are directly caused by playing a musical instrument.
Methods
To perform a systematic review on instrument-related skin diseases in musicians we searched the PubMed database without time limits. Furthermore we studied the online bibliography "Occupational diseases of performing artist. A performing arts medicine bibliography. October, 2003" and checked references of all selected articles for relevant papers.
Results
The most prevalent skin disorders of instrumental musicians, in particular string instrumentalists (e.g., violinists, cellists, guitarists), woodwind players (e.g., flautists, clarinetists), and brass instrumentalists (e.g., trumpeters), include a variety of allergic contact sensitizations (e.g., colophony, nickel, and exotic woods) and irritant (physical-chemical noxae) skin conditions whose clinical presentation and localization are usually specific for the instrument used (e.g., "fiddler's neck", "cellist's chest", "guitar nipple", "flautist's chin"). Apart from common callosities and "occupational marks" (e.g., "Garrod's pads") more or less severe skin injuries may occur in musical instrumentalists, in particular acute and chronic wounds including their complications. Skin infections such as herpes labialis seem to be a more common skin problem in woodwind and brass instrumentalists.
Conclusions
Skin conditions may be a significant problem not only in professional instrumentalists, but also in musicians of all ages and ability. Although not life threatening they may lead to impaired performance and occupational hazard. Unfortunately, epidemiological investigations have exclusively been performed on orchestra musicians, though the prevalence of instrument-related skin conditions in other musician groups (e.g., jazz and rock musicians) is also of interest. The practicing clinician should be aware of the special dermatologic problems unique to the musical instrumentalist. Moreover awareness among musicians needs to be raised, as proper technique and conditioning may help to prevent affection of performance and occupational impairment.

12.  Systematic review of orogenital HIV-1 transmission probabilities 
Background The objective was to assess the risk of HIV transmission from orogenital intercourse (OI).
Methods Systematic review of the literature on HIV-1 infectiousness through OI conducted according to MOOSE guidelines for reviews of observational studies. The PubMed database and bibliographies of relevant articles were searched to July 2007.
Results Of the titles, 56 214 were searched from which 10 potentially appropriate studies were identified; two additional studies were identified through bibliographies and one through discussion with experts. There were 10 included studies, providing estimates of transmission probabilities per-partner (n = 5), incidence per-partner (n = 3), per-study participant (n = 3, following initially seronegative individuals whose partners are of unknown serostatus) and per-act (n = 3). Only four of 10 studies reported non-zero estimates: two per-partner estimates (20%, 95% CI: 6–51, n = 10 and a model-based estimate, 1%, range 0.85–2.3%), one per-study participant estimate (0.37%, 95% CI: 0.10–1.34%) and one per-act estimate (0.04%, 95% CI: 0.01–0.17%). Upper bounds for the 95% CI for zero estimates tended to be relatively large due to the small study sample sizes: 9.0, 12.1 and 2.8% for per-partner; 4.7, 9.6 and 1.8 per 100 person-years for incidence per-partner; 4.4% per-study participant and 0.45 and 0.02% for per-act. Given the small number of studies, a meta-analysis was not considered appropriate.
Conclusions There are currently insufficient data to estimate precisely the risk from OI exposure. The low risk of transmission evident from identified studies means that more and larger studies would be required to provide sufficient evidence to derive more precise estimates.

13.  Review of the evidence that pH is a determinant of nicotine dosage from oral use of smokeless tobacco 
Tobacco Control  1997;6(3):219-225.
OBJECTIVE: To determine whether manipulation of the pH of moist-snuff products by manufacturers could control the delivery of nicotine. DATA SOURCES: Medline database 1966-97 using the following subject headings and keywords: nicotine, absorption, mouth mucosa, skin, hydrogen-ion concentration, smokeless tobacco, biological transport, and membranes; computer database of the tobacco bibliography maintained by the US Centers for Disease Control and Prevention's Office on Smoking and Health; bibliographies of pertinent journal articles, books, and governmental reports; personal communications with experts in nicotine pharmacology and addiction; and Brown & Williamson Tobacco Corporation documents in the Tobacco Control Archives of the University of California, San Francisco. STUDY SELECTION: Included all relevant animal studies, in-vitro studies, nicotine replacement therapy trials, and human observational studies. DATA SYNTHESIS: We found that the effects of pH on drug absorption have been well established in animal models for nicotine and many other acidic or basic compounds. Increased alkalinity promotes the absorption of nicotine and increases its physiological effects. Human studies, which are more limited, confirm these processes. For example, nicotine absorption is directly related to the pH when nicotine is delivered in either tobacco smoke or nicotine polacrilex gum. CONCLUSIONS: Although other factors could influence the rate of nicotine absorption from oral tobacco, manipulating tobacco pH appears to be the primary means by which the speed of nicotine absorption is determined in moist-snuff products.

16.  Computer-stored faculty publication file using the MT/ST in a medium-sized medical center library. 
The Bowman Gray School of Medicine Library has implemented a computerized faculty publication file adapted from an existing system that utilized a Magnetic Tape/Selectric Typewriter for catalog card production and computer storage. The faculty publication file has provided printouts for the school's annual report and monthly faculty bulletins. After the data for all faculty bibliographies have been stored in the file, it will be possible to retrieve complete author and departmental listings. The file will be continuously updated by adding current citations and the bibliographies of new faculty members and by deleting data when faculty members leave the staff.

17.  Educating Hungarian Medical Librarians in Special Literature 
In Hungary the completion of a thirty-month course is required of those who wish to qualify as medium-level librarians. Medical librarians are given a special course which differs from the general course in that it covers the subjects of medical terminology and information in special literature. The latter subject is accorded the highest number of teaching hours, since the subject matter is vast and since, in addition to theory, much time must be spent on exercises and the presentation of reference books. The students become familiar with the main Hungarian and foreign information systems in the medical and related fields and with special bibliographies, encyclopedias, handbooks, and dictionaries. We take special care to familiarize students with the abstracting journals and indices. For several semesters they have homework and lesson exercises in the use of the Hungarian Medical Bibliography and Index Medicus.

20.  Development of Methodologic Tools for Planning and Managing Library Services: IV. Bibliography of Studies Selected for Methods and Data Useful to Biomedical Libraries * 
This selective bibliography is intended to serve as a guide to empirical studies reporting data and methods that can be used by medical librarians to assess their own efforts objectively and to improve the effectiveness and efficiency of services they offer. The decision rules that governed selection of items for the bibliography are specified in detail. A total of 178 items published between 1915 and mid-1968 met the selection criteria. The list of items is supplemented by a keyword index derived from titles. Half the items are journal articles; a third of these articles appeared in the Bulletin, and most of the remainder in thirteen other library and information science journals. Most of the non-journal items are technical reports issued by the organization that conducted or sponsored the work. The characteristics of this literature suggest that few medical libraries, unless they are part of a university system that includes the collection of a library or information science school, are likely to have quick access to the literature base needed to support a comprehensive program of self-evaluation studies and the continuing education of their own staff. Regional medical libraries might well undertake to ensure both ready access to, and awareness of, literature on the scientific aspects of librarianship.

22.  The role of annotated bibliographies in information dissemination. 
In July 1982, a comprehensive questionnaire was sent to a random sample of names on the National Diabetes Information Clearinghouse (NDIC) mailing list to measure user satisfaction with and use of annotated bibliographies about diabetes topics. The bibliographies are used to learn more about a topic and to locate cited materials. The total number of publications ordered by this sample is 8,857; therefore, an extrapolation from these data suggests that more than 45,000 publications were ordered as a direct result of the citations as the source of information.

23.  The selection of high-impact health informatics literature: a comparison of results between the content expert and the expert searcher 
Background:
The Agency for Healthcare Research and Quality (AHRQ) National Resource Center for Health Information Technology (NRC) created the Health IT Bibliography that contains peer-reviewed articles in eleven different health informatics categories. To create the bibliography, informatics experts identified what they considered the seminal articles in each category.
Methods:
Using the same eleven categories, an expert searcher (librarian) compiled a list of the “best” health informatics articles using information seeking and retrieval tools. The two sets of articles were then compared using high citation counts as a measure of value.
Results:
The expert searcher set (8,230) contained more than 3 times the citations to chosen articles compared to the content expert set (2,382). Of 60 articles, 27% of those articles (n = 16) were included in both sets. The frequently cited journals were similar for both sets, and one-third of the same authors were cited in both sets.
Discussion:
While citation counts and the timeliness of the articles differed in the two sets, the same authors and same journals were frequently present in both sets.
Conclusion:
A best practice for locating high-quality articles may be collaboration between expert searchers and content experts.

25.  Reasons Why Post-Trial Access to Trial Drugs Should, or Need not be Ensured to Research Participants: A Systematic Review 
Public Health Ethics  2011;4(2):160-184.
Background: researchers and sponsors increasingly confront the issue of whether participants in a clinical trial should have post-trial access (PTA) to the trial drug. Legislation and guidelines are inconsistent, ambiguous or silent about many aspects of PTA. Recent research highlights the potential importance of systematic reviews (SRs) of reason-based literatures in informing decision-making in medicine, medical research and health policy. Purpose: to systematically review reasons why drug trial participants should, or need not be ensured PTA to the trial drug and the uses of such reasons. Data sources: databases in science/medicine, law and ethics, thesis databases, bibliographies, research ethics books and included publications’ notes/bibliographies. Publication selection: a publication was included if it included a reason as above. See article for detailed inclusion conditions. Data extraction and analysis: two reviewers extracted and analyzed data on publications and reasons. Results: of 2060 publications identified, 75 were included. These mentioned reasons based on morality, legality, interests/incentives, or practicality, comprising 36 broad (235 narrow) types of reason. None of the included publications, which included informal reviews and reports by official bodies, mentioned more than 22 broad (59 narrow) types. For many reasons, publications differed about the reason’s interpretation, implications and/or persuasiveness. Publications differed also regarding costs, feasibility and legality of PTA. Limitations: reason types could be applied differently. The quality of reasons was not measured. Conclusion: this review captured a greater variety of reasons and of their uses than any included publication. Decisions based on informal reviews or sub-sets of literature are likely to be biased. Research is needed on PTA ethics, costs, feasibility and legality and on assessing the quality of reason-based literature.
