Advanced literature search and systematic reviews

An introduction to systematic reviews

Selecting databases

Databases are the key resources you need to use for your literature search. Databases will retrieve published studies from a variety of journals. This section provides lists of the main resources you need to search. 

There is no set number of databases you are expected to search. It is common practice to search between four to eight databases to find published papers. 

Key databases

The key databases for health research are available via EBSCOhost and Ovid Online. Select databases that cover general health topics, and the ones focussing on the topic you are interested in. You can create a personal account with each database platform to save and manage your search strategies.
