MeSH is a great resource,a thesaurus, especially significant if you access Medline – from whatever source. (PubMed is the free version, accessible everywhere anyone has access to the internet.)
MeSH means Medical Subject Headings. They are assigned by indexers at the National Library of Medicine. This thesaurus is complete with definitions or scope notes. It is organized in a hierarchical fashion so that if you wanted to search all antibiotics, for example, you wouldn’t have to separately type all of them, but could just “explode” the main heading. You can limit the headings to a major concept, the most important concept(s) in the article. You can also attach subheadings, such as adverse effects of antibiotics.

It’s new and books are not retrievable labled as such in PubMed, but they will be retrieved in Medline searches. Bookshelf is separately searchable.
For example, if you search (in PubMed/Medline) feingold syndrome in the title, you will retrieve the book, chapter, or document, as well as articles, too. NIH is now using color highlights to clearly indicate full text availability.
Feingold syndrome searched in the field labeled book, will retrieve 0.
The following search terms can be used to retrieve the Bookshelf citations in PubMed, e.g., pmcbook feingold syndrome:
