List of MeSH codes

The following is a **list of the codes for MeSH (Medical Subject Headings)**, an in-depth controlled vocabulary and index of journal articles and books in the life sciences.

It is a product of the United States National Library of Medicine (NLM).

The prefixes (C01, A01, etc.) are linked to more specific sub-lists of codes. The medical terms are linked to articles about those topics on the website. Searched terms (your searches) are listed on the website, as well as medical articles for specific or non-specific terms are included with searches.

The items are linked (all the same) by: 
* Tree number(s), which includes the prefix (e.g. A01) and path to the item with the numbers before the item entry number
* Unique ID, which starts with D0 (most of the time)
* RDF Unique Identifier (ID), which is the hyperlink version of the unique ID 
* Entry version (name) and entry terms, which are all of the human-readable names that are connected to the entry 
* NLN Classification #

Realistically, MeSH codes (both this list or articles, and sub-lists for prefixes) would show in search results for every medical term that is included in the MeSH database. This would allow medical terms on the page to help find where an item appears (in its parent lists) and what is similar to it, as in those that are close to the entry. The alternate names (which help with navigation and search of the site) are useful for Wikidata, a sister Wiki project. Each entry on the lists of MeSH codes has a link to the NLN_NIH website item for the entry. MeSH entries can be linked to using any of the items names or identifiers.
