Eugene Garfield, a Pioneer in Information Science

Eugene Garfield can certainly be considered one of the giants of information science. Garfield’s life, as shared in his obituary by Subbiah Arunachala, is intertwined with the history of the development of machine indexing and use of the computer’s capability to enable access to scientific papers by exploring the basic tool of the citation.  This pioneer in information studies created Current Contents, Science Citation Index and his company ISI. He did groundwork that led to the Medical Subject Headings (MeSH). He made great leaps by recognizing the value of the citation itself and developing a way to make them more accessible to researchers.

Unpaywall, a new tool to locate free full text

Here’s a new way to find full text content offered freely somewhere online! 

Easily install Unpaywall’s little lock symbol to your tool bar (Chrome or Firefox required). Then if you encounter an article for which a free full text source is available, a larger lock will appear on the right. A simple click takes you to the article. Since Unpaywall only matches with legally uploaded versions, it can be a great addition to your web search tools and will compliment other resources you may use.
   
Unpaywall should be officially released in early April, and developer Impactstory welcomes input.

Journals - What’s New in Your Favorites? Easy eTOCs!

A new PubMed Labs experiment offers a super awareness tool, PubMed Journals. It is a fast and current way to follow the latest releases from your favorite health science journals that are indexed in MEDLINE – or at least know when they show up in PubMed. First you do need to have a My NCBI account, a service that offers lots more useful features and doesn’t send you junk mail. Once you have that, set it to stay signed in so any time you go to PubMed you’ll be in your account. If you want to see what the library offers, be sure to use our unique address (or this one if you are on staff at the med school).

Then locate PubMed Journals in the lower left of the PubMed home page. Enter a title in the search box at PubMed Journals (if you type slowly a suggestion list will appear!). No additional sign-in is needed, no registration at the publisher website. No email alerts clogging up your in-box! Your list of titles followed is right on the page. Easily discontinue by clicking “Following” to “Follow” – the title will disappear from the list the next time you return to the page. The page also lists popular journals for easy access.

A tip – to return to PubMed from PubMed Journals or My NCBI, just scroll to the very bottom to click on PubMed in the “Popular” column.

Add PubMed Journals to your own “Popular” list of websites today!

Journal Metrics - CiteSource and Journal Impact Factor

A new service has appeared to help judge the impact of a journal in the world of scientific publishing. CiteScore metrics from the publisher Elsevier is a new tool to compare with the well known JIF, Journal Impact Factor.

Similar to the Journal Impact Factor, the CiteScore is “a measure reflecting the yearly average number of citations to recent articles published in that journal.” CiteScore uses 3 years and JIF uses 2 previous years. Limiting the number of years included helps eliminate bias towards journals that have been published a long time.

Another difference is that whereas JIF is available only to Journal Citation Reports™ subscribers, the CiteScore is free online. CiteScore is based on the Elsevier Scopus database, and the JIF uses the journals in Web Of Science, which is not owned by a publisher.  

The concept of an impact factor was initially devised by Eugene Garfield, founder of ISI, the Institute for Scientific Information, and creator of Science Citation Index. An impact factor is a calculation that can be used along with many other factors to evaluate journals within a field. However, a single article can greatly affect the rankings.

For more information on impact factors see the JIF video. For more information on the new CiteScore, check the recent article in Nature.

HealthReach - Health Information for Non-English and Second Language Speakers

HealthReach started as a resource for refugees ("RHIN") but is now expanded to meet the needs of the broader non-English speaking and second-language audience. It offers multilingual consumer health and patient education materials on individual topics and in a few special collections. Some material is in English, aimed at those who serve a specific population. 

MedlinePlus remains a valuable consumer health resource that focuses more on specific conditions and offers information in multiple languages. Entering a search term such as "Asian health" there will also result in a list of resources. Both databases are services of the National Library of Medicine.

Systematic Review Series in AJN

"Systematic Reviews, Step by Step" is a series offered in AJN, American Journal of Nursing. It comes from the Joanna Briggs Institute, an international collaborative supporting evidence-based practice in nursing, medicine and allied health.

The initial March, 2014, article provided an overview. "A systematic review does not seek to create new knowledge but rather to synthesize and summarize existing knowledge, and therefore relevant research must already exist on the topic."

Articles in the series:

1st The Systematic Review: An Overview
2nd Developing the Review Question and Inclusion Criteria (PICO)
3rd Constructing a Search Strategy and Searching for Evidence: a Guide to the Literature Search for a Systematic Review
4th Study Selection and Critical Appraisal
5th Data Extraction and Synthesis
6th (final) Presenting and Interpreting Findings

Series authors include Edoardo Aromataris, director of synthesis science at the Joanna Briggs Institute in the School of Translational Health Science, University of Adelaide, South Australia; and Alan Pearson, former executive director and founder of the Joanna Briggs Institute.

Surgical Stapling Pioneer Dr. Mark M. Ravitch

"His surgical legacy as a founder of pediatric surgery as a specialty, as a surgical innovator, and for introducing the concept of surgical stapling in the U.S. is paralleled by his simultaneous contributions to surgical education and knowledge." The Mark M. Ravitch Papers, 1932-1989, is the latest collection featured in the History of Medicine section of the National Library of Medicine for those interested in the history of surgery, surgical techniques, and pediatrics.
