To find law reviews you can search one of two ways. First, you can select "Law Reviews" in the What are you interested in? section (see below), and search by keyword.

Alternatively, if you have a specific citation, journal, date range, etc., that you need to search for, click on the Advanced Search button below the large main Search box (see above). From that page (see below), click Select a specific content type, and select one of the links under Law Reviews and Journals, most likely the "Law Reviews and Journals" option. Once you've made a selection, the advanced search boxes will reflect the available search features for that type of content, including boxes for citation information, journal title, etc.
