Many of the major art databases index book reviews, namely Art Index, Bibliography of the History of Art, Avery Index to Architectural Periodicals, and ArtBibliographies Modern. CAA Reviews, an online-only publication of the College Art Association, includes reviews of art and architectural monographs, exhibitions, and essays organized by subject. The Art Libraries Society of North America publishes its art book reviews online: ARLIS/NA Reviews. Also, Bookforum reviews a good number of art books, with some reviews available at its website. The Art Libraries Society also has a useful resource that reviews art and architecture-related apps, websites, and other online resources of interest to arts researchers and library patrons: Multimedia & Technology Reviews.
One can also search Articles+, do a search, entering as many keywords as you'd like contained in the book title in question, and select Book Review under Content Type on the left-hand side.
