Browsing the MeSH tree.

Medical Subject Headings (MeSH) is a controlled hierarchical vocabulary of biomedical terms/headings used for the description of document’s content and for more precise retrieval. Headings are grouped into 16 categories and in addition every heading can be supplemented by one or more subheadings, e.g. diagnosis, therapy, psychology etc.

A cloud of MeSH headings is derived from frequency of headings’ occurence in the database or in the set of retrieved records.

The size of characters of the headings depends on frequency of use of a particular heading in the set of indexed records.

By clicking on any of these headings you get records that contain the selected MeSH heading.

If you already have some records, by clicking on a heading you limit/specify your query to the records that contain the selected heading.
