Choose the fielded search option on the left-hand side of the page. Within this page use the “Limit To” tool and limit to “Methodology.” Then choose “Literature Review” from the menu.
Using the Advanced Search feature, you can select “Information Analyses” from the Document Type menu. This heading encompasses literature reviews.
