You will probably want to search disciplinary databases (i.e. Worldwide Political Science, Criminal Justice Abstracts, and Sociological Abstracts) in addition to the more multi/interdisciplinary resources on this page. These links will take you to the disciplinary database library guides here at the WSU Libraries. For disciplines not on included, look here.
Finding Reviews: Some databases will let you filter by "book review" as an article type, but the search will not always be comprehensive. Generally its good to search for the title of the book in quotation marks (usually the part before the subtitle is fine), with the word review*, i.e. "Net Delusion" review* (The asterisk is a common truncation symbol and will let you search for both the word review and the word reviews in most databases). Sometimes you may want to search by the author's name in addition to (or instead of?) the title.
