New PubMed Link: “Articles Frequently Viewed Together”

PubMed has introduced a new type of link called “Articles Frequently Viewed Together” to assist with locating important articles on a given topic. For some PubMed abstracts, this feature will appear in the “Related Information” section in the right column. Currently, only 1.3 million out of the 24 million records in PubMed have this link. The calculation is based on anonymous click data for the last year, so older articles will be especially underrepresented. To find all articles with these relationships, search PubMed with the query “pubmed_pubmed_alsoviewed[filter]” and add additional terms to narrow the focus to your area of interest.

NLM Theater Presentations at MLA 2015

The NLM exhibit booth at the 2015 Annual Meeting of the Medical Library Association in Austin, TX, featured theater presentations to bring users up-to-date on several NLM products and services. The presentation recordings are captioned and accessible from the NLM Distance Education Program Resources page. The presentations include:

Note: To listen to the voice recordings and view the captions you may need the latest version of Flash® Player (download for free from the Adobe Web site). To maximize the presentation, use the Full Screen button. For more information, go to the NLM Technical Bulletin page.

New Name for PubMed Related Citations Discovery Tool

The PubMed “Related citations” feature will soon be renamed to “Similar articles.” “Similar articles” was chosen because “Related citations” is ambiguous. There are several types of relationships that articles may have. The algorithm to generate the results has not been modified. The link name will be updated on the Summary results. The Abstract display discovery tool title will also be renamed. To see illustrations of the new feature, visit the NLM Technical Bulletin.

NLM Updates MEDLINE/PubMed Health Literacy Information Resources

The MEDLINE/PubMed Search and Health Literacy Information Resources page and its preformulated Health Literacy Special Query have been updated to keep pace with the growing body of relevant literature. The Health Literacy Special Query now retrieves additional citations to articles about numeracy, comprehension of informed consent, and health insurance comprehension. The dynamic MEDLINE/PubMed health literacy search retrieves more than 8,000 citations to English language journal articles related to Health Literacy. PubMed filters can be used to limit to particular years, research or publication types. To limit citations to a particular subject (such as “decision making”) use the Advanced Search features.

Sometimes called Quantitative Literacy (QL) or Quantitative Reasoning (QR), numeracy involves skills needed to select a health insurance plan, choose treatments, and understand medication instructions. MEDLINE/PubMed may contain citations to articles that discuss numeracy skills of clinicians—physicians, nurses, and other health professionals who must communicate with patients and the public. Informed consent comprehension is of great interest to health literacy advocates and researchers who are concerned with how effectively health care providers communicate disease and treatment risks and benefits to patients. Among the more than 16,000 citations to articles with Informed Consent as a major descriptor, many citations don’t explicitly use the phrase “health literacy,” but are conceptually tied to it.

The selected resources on the right side of the MEDLINE/PubMed Search and Health Literacy Information Resources page includes new links, such as:

PubMed Mobile Updated

​PubMed Mobile has been updated with several new features including additional filters, sort selections, trending articles, and related searches. Illustrations are included in a recent article published in the NLM Technical Bulletin.

Filters include: Article types (Books and documents, Clinical trials, Meta-analysis, Randomized controlled trials, Review articles, Systematic reviews); Text availability (Free full text, Full text); and Publication dates (5 years, 10 years). “Trending Articles” appears on the homepage. Discovery tools display below the results on mobile devices with smaller screen sizes.

PubMed’s Send to Order Feature

PubMed users continue to report an issue where the menu choices do not display when using the PubMed “Send to” feature. When this was first reported, it was determined that the problem occurs for those using older browsers (Internet Explorer 7 and 8) not supported by PubMed, or using “Compatibility View” in newer browsers (IE10 or 11). Users encountering this issue should upgrade to a more current version of Internet Explorer (IE10 or IE11) or use Firefox. DOCLINE users with new or upgraded browsers should configure their browser settings according to DOCLINE System Requirements to ensure full functionality. PubMed users should refer to the Browser Advice for NCBI Web Pages site.

DOCLINE users who are unable to upgrade or change browsers at this time can work around the issue by opening two separate browser tabs or windows, one for PubMed and the other for DOCLINE. This will allow them to search PubMed in one window/tab, then copy & paste the PMIDs from PubMed into DOCLINE in the other window/tab. Users of IE10 or IE11 experiencing the issue should check that “Compatibility View” is turned off, as follows:

  1. Open Internet Explorer
  2. Click Tools
  3. Click Compatibility View settings
  4. Uncheck “Display all websites in Compatibility View” or remove DOCLINE from the list of “Websites you’ve added to Compatibility View”
  5. Close & reopen Internet Explorer

Note to QDPortal users – if you experience the PubMed “send to” issue with a current browser version, contact QuickDoc customer at support@nesurv.com, or by phone at (617) 738-1800.

The National Library of Medicine Wants Your Stories!

Do you know any stories about people using NLM resources to find out something interesting, forge a new path, or improve their lives in a unique or dramatic way? Or, more simply, have you ever found just the right information at just the right time, for yourself or for a patron? For this year’s theater presentations at the Medical Library Association annual meeting in Austin, TX, NLM staff members who develop the resources are interested in teaming with the librarians who use them. They are interested in stories (great and small) about any NLM resource, but especially:

  • HSRProj
  • Health Services Research Resources on Comparative Effectiveness, Patient Centered Outcomes, Health Technology Assessment
  • DIMRC and other disaster resources
  • BIBFRAME and Linked Data
  • History of Medicine social media (e.g., Circulating Now)
  • MedlinePlus
  • PubMed Central
  • PubMed
  • PubMed Health

Anyone interested in sharing their story should contact Kate Majewski at NLM.

PubMed Subject Filter Strategies Updated for 2015

PubMed subject filter strategies are reviewed each year to determine if modifications are necessary. Modifications may include revisions due to changes in Medical Subject Heading (MeSH) vocabulary or MEDLINE journals, adding or deleting terms, and changing parts of a strategy to optimize retrieval. The following subset strategies were recently revised:

List of Serials Indexed for Online Users, 2015 Edition, Now Available in XML

The List of Serials Indexed for Online Users (LSIOU), 2015 edition, is now available in XML format. The 2015 edition contains 14,856 serial titles, including titles currently indexed for MEDLINE as well as titles indexed over time which have ceased or changed titles. The titles are listed alphabetically by the journal title abbreviation. Tailored lists of indexed journals may be generated from the NLM Catalog. While the XML version of the LSIOU is a snapshot in time, the results of a search in the NLM Catalog will provide a “real time” list for the LSIOU.

For a “real time” list for the LSIOU, enter reportedmedline in the search box and click “Search.” For a list of only the currently indexed MEDLINE journals, enter currentlyindexed in the search box and click “Search.” Display and sort formats are selected from the results page; click on the Display Settings pull-down menu to choose a display format (for example, the Journal display) and an appropriate sort (for example, Title or Title Abbreviation). To save the entire list as one document, click on the “Send to” pull-down menu, with “File” as the destination, choose a format and sort order, and then click “Create File.” Click “Save” in the File Download pop-up box. Provide your directory location and desired file name.

Additional information about journals indexed for MEDLINE can be found via the links from the MEDLINE/PubMed Resources web page. This page includes Journals Recently Accepted by NLM for Inclusion in MEDLINE, a list of titles selected by the Literature Selection Technical Review Committee (LSTRC) that meets three times per year in February, June, and October. Results from those meetings appear online about six weeks after each meeting, both on the web page and in the NLM Catalog. For additional details about searching the NLM Catalog, visit NLM Catalog Quick Tours and Searching for Journals in the NLM Catalog.
