Notes: 

Most book reviews are published in periodicals such as journals, newspapers, and magazines. Cite these reviews as you would an article in the corresponding source type. If the title of the review is the name of the book being reviewed, start the title portion of your citation with Review of followed by the title of the book being reviewed (see second example) (MLA 29). If you are citing multiple reviews without a title, include the title of the book being reviewed through the first word or noun phrase for your in-text citation (e.g. (Review of Hidden Figures)) (MLA 118-19). For electronic sources, you should provide a DOI (Digital Object Identifier) if available; otherwise, provide the direct URL for the item, but omit the http:// or https:// (MLA 110). If the review was published on a website or blog (and could change or be removed in the future), include an access date at the end of your citation (MLA 53); you do not need an access date if the review appeared in a published periodical that is stable and will not significantly change, particularly if there is a corresponding print version.
