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).

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).
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.
Where do you start your searches? There are many options. Watch this 3 minute video to learn how to build a search from within the MeSH database.
This video answers one of the most common questions we hear about MeSH: what do the dates mean?
Take a look, and if you’d like to learn more, check out the MeSH tutorial from the National Library of Medicine.
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.
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.

Take a break (22 minutes) and watch this video presentation by Victoria Brazil, a physician and medical educator from Australia. She talks about what educational modalities and interventions are effective in medical education. Spoiler alert: the answer is everything and nothing.
One question we’re often asked in our classes is how to keep up with changes to PubMed and other NLM Resources. There are lots of changes, but there are several resources as well. Whether your interest is PubMed, History of Medicine, disaster medicine, or NCBI databases, you can find a blog, Facebook page, Twitter account, or even Pinterest board to follow. For the full list of ways to connect with NLM, see their social media page.
In addition to the NLM accounts, you can also follow the social media of your National Network of Libraries of Medicine Region or one of the Centers (like us, the National Library of Medicine Training Center).
Finally, we always recommend subscribing to the National Library of Medicine Technical Bulletin. You can be among the first to know about changes to PubMed and other important information that may impact your use of NLM resources. They also have a searchable archive that can be useful for finding when particular changes occurred. For example, you can search for “bolded” to learn that PubMed began making your search terms appear in bold in 2011.
