The search engine PubMed contains over 29 million biomedical references from the MEDLINE database. In one go, you can search over 5600 life science journals from 80 countries as well as online books. Coverage runs from 1946 onwards. PubMed is updated on a daily basis.
PubMed is produced and updated daily by the U.S. National Library of Medicine
Access to PubMed is free, but to make the most of the links to the full text articles you need to access PubMed via the Utrecht University Library website. If you do so, you will find the next to each reference. This will bring you directly to the full text, if available. Older volumes which are not online yet and are housed in the depots of the University Library may be requested via WorldCat. For this you need a library card. Click in the UBU-LINK menu on 'Availability via Utrecht University Library' - 'Items' and select the correct year. See also: Loan and more.
You will be offered even more options via the UBULINK-menu. Search in Worldcat and if necessary, you can order items. There are costs associated with this last option. All information on the UBULINK can be found here.

For easy access to most digital resources, there is also the Library Access browser plugin, which often gives access to paid resources without additional login, even outside the UU or UMCU network. See for this: Library Access.
MeSH is the controlled list of keywords in PubMed.
MeSH is short for Medical Subject Heading.
Keywords are connected in a hierarchic structure.
This thesaurus helps you to specify your search in PubMed.
All MeSH categories
The right search combines:
Keywords [MeSH]: by which you also find references without abstracts (depending on the subject the number can run up to ca. 50 percent)
Title/Abstract [tiab]: by which you also find the most recent references to which keywords have not been added yet.
