Representatives of the US National Library of Medicine (NLM) and the Wellcome Trust recently signed a memorandum of understanding to work together to make thousands of complete back issues of historically-significant biomedical journals freely available online. The terms of the MOU include a donation of £750,000 ($1.2 million) to the NLM that will support coordination of the three-year project to scan original materials from NLM’s collection at the article level, and Wellcome’s work to secure copyright clearances and permissions for electronic deposit from publishers. NLM will undertake conservation of the original material to ensure its preservation for future generations. Key journals charting the development of modern medicine over the last 150 years will be digitized in their entirety and made available on the National Institutes of Health life sciences repository PubMed Central (PMC) and its European counterpart, Europe PMC. The project builds on the Medical Journal Backfiles Digitization Project (2004-2010) and will contribute substantially to the current PMC archive of over 3 million articles from medical journals.
Part of the project will concentrate on mental health journals, supporting a major archive digitization program also being undertaken by the Wellcome Trust. Journals to be digitized include Mental Health, Mental Hygiene, and the Journal of Psychological Medicine and Mental Pathology. Other journals have been selected for their general relevance, such as the Indian Medical Gazette, the British and Foreign Medico-Chirurgical Review and the Transactions of the Epidemiology Society of London. In addition to images and searchable text, NLM will also create article-level citations for PubMed. Digitization is expected to start in late 2014 and to be completed by 2017. Material will be added to PMC and Europe PMC as it is digitized.
The Wellcome Library is one of the world’s leading libraries of medical history, housing 2.5 million items of extraordinary range and diversity, and a growing collection of contemporary biomedical information resources relating to consumer health, popular science, biomedical ethics and the public understanding of science. The Wellcome Library is part of the Wellcome Trust, a global charitable foundation dedicated to achieving extraordinary improvements in human and animal health. It supports the brightest minds in biomedical research and the medical humanities. The Trust’s breadth of support includes public engagement, education and the application of research to improve health. It is independent of both political and commercial interests.
The National Library of Medicine has announced the launch of a new user interface for the IndexCat database, which offers a faster response time to searches; full record displays in search results; and record sorting and refinements. NLM uses the same search engine for its main Web site, as well as MedlinePlus, MedlinePlus en Español, the Directory of the History of Medicine Collections search engine, and the History of Medicine Finding Aids Consortium.
IndexCat simultaneously searches the digitized version of the printed Index-Catalogue of the Library of the Surgeon General’s Office; eTK for medieval Latin texts; and eVK2 for medieval English texts; and LocatorPlus. A post in the NLM Circulating Now blog offers additional information on IndexCat. There also are a number of new and revised FAQs and Help pages to assist with searching IndexCat. Additional details and illustrations are available in the most recent edition of the NLM Technical Bulletin.
The current trend in evaluation reporting is toward fewer words and more images. There are a number of companies that offer high-quality, royalty free photographs at minimal cost. Stockfresh, for example, charges as little as $1 per image. However, no-cost is even better than low-cost. Freelancers Union, a nonprofit organization dedicated to assisting freelance workers, recently published a list of the best websites for no-cost images. If you are looking for free images for your presentations or reports, check out their article, which also describes the difference between public domain, royalty-free and Creative Commons-licensed images.
NLM has released a new Drug Information Subject Guide as the latest update in its subject guide series. These guides are based on the most frequently asked questions, and are starting points for health professionals, researchers, librarians, students, and others. Other published guides in this NLM series are about finding:
A Genetics/Genomics subject guide will be available later this year. NLM will develop more subject guides as needed. NLM welcomes comments, questions, and suggestions about all of the guides.
Three hundred four (304) new MeSH Headings were added in 2014. Forty-eight (48) MeSH Headings were either changed or deleted and replaced with more up-to-date terminology. Three new publication types have been introduced for 2014 MeSH:
- Dataset: This publication type is defined as “An organized collection of values stored permanently in a formalized manner suitable for communication, interpretation, or processing.” This publication type will not be used in combination with any other publication type as it is not to be used for journal articles that contain or produce datasets as part of the publication (including Supplemental Materials). Rather, it will be used on citations to items that are stand-alone descriptions of the metadata of a particular dataset.
- Observational Study: The scope note defines this publication type as “A clinical study in which participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions (as in an interventional study).” This publication type should not be confused with the MeSH Heading “Observation” which is used for a scientific method. There is a related new MeSH Heading “Observational Studies as Topic,” which is used for general design, methodology, economies, etc. of observational studies.
- Pragmatic Clinical Trial: This publication type refers to “Randomized clinical trials that compare interventions in clinical settings and which look at a range of effectiveness outcomes and impacts.” There is a related new MeSH Heading, “Pragmatic Clinical Trial as Topic,” which is used for general design, methodology, economics, etc. of pragmatic clinical trials.
Additional details are available by consulting the 2014 online Introduction to MeSH and the NLM Technical Bulletin.
The NIH Big Data to Knowledge (BD2K) initiative has released a Funding Opportunity Announcement (FOA) to support a U24 resource award for Development of an NIH BD2K Data Discovery Index Coordination Consortium. The purpose of this FOA is to create a consortium to begin development of an NIH Data Discovery Index (DDI) to allow discovery, access, and citation of biomedical data. Letters of intent to apply are due by February 6, 2014, and completed applications are due by March 6, 2014. Budgets are limited to $2,000,000 in direct costs per year but must reflect the actual needs of the proposed project. The maximum project period is three years.
As part of the NIH Big Data to Knowledge (BD2K) initiative, the DDI seeks to fulfill the recommendation from the Data and Informatics Working Group (DIWG) Report to the Advisory Council to the Director to “Promote Data Sharing Through Central and Federated Catalogues.” The awardee in response to this FOA will constitute a DDI Coordination Consortium (DDICC, U24) to conduct outreach, fund small pilot projects, manage communication with stakeholders, constitute and coordinate Task Forces to study relevant questions related to access, discoverability, citation for all biomedical data and assure community engagement in the development, testing, and validation of an NIH DDI. Part of this effort will be to assemble a user interface (website) through which the results of development and testing of models for an NIH DDI may be communicated.
The National Library of Medicine Library has announced the enhancement of In His Own Words: Martin Cummings and the NLM, a digital edition of selected speeches and articles by the man who served as its director from 1964 to 1983. During his tenure, Dr. Cummings guided NLM into the computer age and significantly broadened its mission. Originally launched in February 2012, In His Own Words now includes Dr. Cummings’ annual Congressional appropriations testimonies, along with commentary provided by Dr. Cummings through interviews with Dr. Cheryl Dee of San Jose State University School of Library and Information Science and Florida State University School of Library and Information Services. These enhancements document Dr. Cummings’s opinion that the testimonies and commentaries together offer the most valuable window into NLM’s program development from the 1960s to the 1980s. Reflecting on his testimonies, and the subsequent question and answer sessions defending them, Dr. Cummings’s commentary provides contextual insight on significant turning points in the Library’s history and the political personalities that influenced them.
Martin Marc Cummings, MD (1920–2011), was a medical educator, physician, scientific administrator and medical librarian. Highly respected in all of these disciplines, he made significant contributions to medical informatics and librarianship. As a whole, In His Own Words represents the NLM’s ongoing commitment to collecting materials related to its institutional history and programmatic impact—as part of the NLM Archives—as well as to digitizing these collections and making them widely available for the benefit of researchers, educators, and students.

F. W. “Wilf” Lancaster, professor emeritus at the University of Illinois Graduate School of Library and Information Science and former NLM employee, passed away on Sunday, August 25, 2013, in Urbana, IL. Wilf’s contributions to the NLM in the early days of automated information retrieval have had a lasting impact on our information systems and services. His work as a professor and mentor also benefited the Library, as he led many fine graduate students to pursue careers at the NLM. With his passing, NLM remembers a colleague and friend.
Wilf earned a reputation for greatness in the evaluation of information storage and retrieval systems, based in part on his early experience with a comprehensive evaluation of NLM’s MEDLARS (MEDical Literature Analysis and Retrieval System). The evaluation of the MEDLARS Demand Search Service in 1966 and 1967 was one of the earliest evaluations of a computer-based retrieval system and the first application of recall and precision measures in a large, operational database setting. The use of computers for bibliographic retrieval systems was in its infancy, and many of the extant systems were small or experimental. Planning for the evaluation began in December 1965, when Wilf joined the NLM staff as Information Systems Evaluator. Following completion of the MEDLARS evaluation, he developed NLM training programs in his roles as Deputy Chief of the Bibliographic Services Division and Special Assistant to the Associate Director for Library Operations.
In 1970-1971, Wilf conducted an evaluation of the MEDLARS AIM-TWX system, an innovative experimental service that was the precursor of MEDLINE/PubMed. This was an important study of early online systems and their direct use by end users. Written more than 40 years ago, his report reflects his signature forward-thinking attitude toward system design, as relevant today as then: “We should always look for ways of improving retrieval systems and making them more attractive to potential users. The philosophy that ‘the system is used, therefore it is good’ is a very shallow one. We must not assume that a system having appeal today will always retain this appeal….novelty wears off and system designers cannot afford to rest too long on their laurels. In the past, users have been required to adapt to the information system. In the future systems must be designed that adapt to the users.”
For further information on Wilf’s extraordinary accomplishments and influence, see the Festschrift published in his honor by Library Trends in 2008, “Essays Honoring the Legacy of F. W. Lancaster,” (Volume 56, Issue 4). One of the articles, entitled “Excellence in Evaluation: Early Landmarks at the National Library of Medicine,” focuses on his work at NLM and was used as the source for the above summary of contributions to NLM. His obituary is also available online.
