There are A LOT of databases that you could use to find articles to use in your literature review. We recommend starting in a database instead of a general search tool like Google. Databases specialize in academic sources. You can find good sources in Google, but many of articles are behind paywalls. You will need to use the library's systems to read the full article anyways. Save yourself time - start in an academic database!
All our databases are listed on the A-Z Databases List. The chart on this page compares a small number of recommended databases:
