Look through these databases for more articles to use for your literature review!
As literature reviews may already exist on some aspect of your topic, it is often useful to search databases for them. However, while many databases do not permit one to limit to the specific document type of literature reviews, some do. At any rate, it is usually a good idea when searching a database to enter the particular search term(s) in the first search box and then "literature review" (or the truncated "literature review*" that will retrieve "literature review" and "literature reviews") in the second search box.
The database CINAHL allows you to limit your search to the Publication Type "Systematic Review".
Many of the Systematic Reviews will be literature reviews.
