Subject Filter Strategies Updated

Wednesday, March 4th, 2015

PubMed has several Subject Filters that can be used for searching, and each year the filters are reviewed to determine if they need to be updated. This year, the following subject filters have been revised:

  • Cancer
  • Complementary Medicine
  • Dietary Supplements
  • Systematic Reviews
  • Toxicology
  • Veterinary Science

You can find information on all of the filters, including links to the full strategy in the PubMed Resources Guide.  Also, notice that you can apply these filters by adding the subject filter name [sb] to your search. For example, to add the complementary medicine filter to your search, simply add AND cam [sb].

Sharing a PubMed Search Strategy: The Movie

Monday, February 16th, 2015

Did you know that you can easily share a PubMed search strategy by sending the URL for the search? Watch this one minute video to learn how.

An Oldie, but Goodie. MeSH, the Movie.

Monday, February 9th, 2015

This 11-minute video is an introduction to the development, structure and use of the MeSH® vocabulary. The video may be of particular interest to searchers of MEDLINE®/PubMed®, and is used in the PubMed search classes offered by NLM and the National Library of Medicine Training Center (NTC).

Branching Out: The MeSH Vocabulary

2015 MeSH Now Available in PubMed

Monday, December 15th, 2014

As of December 15, PubMed/MEDLINE citations (including the backlog of citations indexed since November 19 with 2015 MeSH), the MeSH database, and the NLM Catalog were updated to reflect 2015 MeSH.

The MeSH translation tables were also updated on December 15. Now that end-of-year activities are complete, MEDLINE/PubMed may be searched using 2015 MeSH vocabulary, however, don’t be surprised if your search comes up empty. It will take a little bit of time for Indexers to begin to use the new terms.  For example, the term Courage was added to MeSH for 2015, but it has yet to be applied to a citation.

This link will show you the details for all MeSH data changes made for 2015. http://www.nlm.nih.gov/mesh/introduction.html Scroll down to item #4 and look at the list of new descriptors/MeSH headings.

On December 16th, NLM will resume daily MEDLINE updates to PubMed (they’ve been on hold due to year-end-processing).

Has Cheezburger?

Monday, December 8th, 2014

No that’s not a typo. And no we’re not going to talk about cheeseburgers (or cats) today. For those of you who don’t know what I’m talking about, visit here: http://icanhas.cheezburger.com

Now, on to the business at hand. PubMed contains commands to find citations with corrections, erratum, comments and patient summaries. View the 2 minute 32 second video to see where to find the commands and how to use them (Once you view the video below, you’ll see the connection between the title of this blog entry and the commands).

After you press Play, click on the controls below the video to change your view to HD (look for the little gear icon). You can also view the video in full-screen mode.

MEDLINE/PubMed Year-End Processing Activities for 2014

Monday, October 20th, 2014

The National Library of Medicine (NLM) is currently involved in MEDLINE year-end processing (YEP) activities. These include changing the Medical Subject Headings (MeSH) main headings as well as Supplementary Concept Records that standardize names and associated numbers for chemical, protocols, and diseases that are not main headings. The MeSH edits include existing MEDLINE citations to conform with the 2015 version of MeSH, and other global changes.

Important Dates:

November 19, 2014: NLM expects to temporarily suspend the addition of fully-indexed MEDLINE citations to PubMed. Publisher-supplied and in process citations will continue to be added.

Mid-December 2014: PubMed MEDLINE citations, translation tables, and the MeSH database will have been updated to reflect 2015 MeSH.

For details about the impact on searching from November 20 to mid-December, see: Annual MEDLINE/PubMed Year-End Processing (YEP): Impact on Searching During Fall 2014.

For background information on the general kinds of changes made annually, see: Annual MEDLINE/PubMed Year-End Processing (YEP): Background Information.
