Many databases index book reviews, including Articles+ and many subject databases that index the literature in/for a particular field. A lengthy book review can be a good source for learning enough about a particular title to warrant tracking it down or not as well as point to other authors and/or books on a similar theme.
To search for book reviews in 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.
