Every year, the National Library of Medicine (NLM) adds new Medical Subject Headings (MeSH) to their thesaurus. At the same time, they do "housekeeping" to tidy up the vocabulary. This year, there are 483 new headings, including "anger management therapy," "cognitive therapy," "olive oil," and "red meat." Changes were made in the way plants and foods are handled, including the addition of a new broad heading, "Diet, Food, and Nutrition," which is used to group headings on those topics together.

The folks at NLM also went through headings that appear in more than one place and and eliminated the "uncle/nephew" phenomenon, where headings appeared multiple times at different places in a single branch of the tree. They have also begun a project to ensure that each MeSH term has a descriptive scope note.

 More information on the 2016 MeSH updates are at https://www.nlm.nih.gov/pubs/techbull/nd15/nd15_mesh.html. Take a look at it, and join us to discuss this year's changes as well as changes you would like to see in the future.
