Introduction to database searching

Databases are collections of resources such as journal articles and conference papers, and also sometimes book chapters and reports. If you are doing a literature search or systematic review they are a key resource to use.

There are two main kinds of database:

  • Bibliographic - these index what has been published for a particular subject area and are used to identify material that you might want to locate and study
  • Full text - as well as providing the bibliographic information they also provide access to the full text of the material you may wish to read

When searching using the NHS Knowledge and Library Hub you will find links to the full text of articles when you look at your search results. If there is no link then you should see if it is available through the University of Oxford via e-Journals A-Z (you will need to be in a Bodleian Library).

NHS resources for advanced searching

For complex, robust and reproducible searches – including for systematic review and informing research – use the native interfaces EBSCO, Ovid and ProQuest for bibliographic databases such as Medline, Embase and CINAHL. These are accessible with your NHS OpenAthens account so you do not need to be in the library to use them.

For a walk-through of how each interface works, see our PDF guides below:

Different databases are tailored to provide coverage of particular aspects of healthcare or disciplines. 

Below are some suggested databases.

You can access these databases via the original supplier interfaces by logging in with your OpenAthens account username and password when prompted.
