Books are shelved in general subject categories using the Library of Congress classification system. You may want to supplement your use of the catalog with browsing shelf areas for your topic.
There are several ways to locate book reviews. Google can be your friend, here, especially if your book was recently published. Amazon also frequently publishes editorial reviews on an individual book's page, although note that these are often excerpts and not the full review. You can track down the full reviews, however, as long as you make note of the cited publication. Community reading sites, like Goodreads or The StoryGraph, primarily contain reader reviews, so make sure you're finding the appropriate kind of source for your work.
