If you need help finding book reviews, consult this guide for suggestions. You'll also find a link to our Citation Guide and some examples of how to cite book reviews.
Generally, book reviews are written around the time the book was originally published. Literary criticism appears in later years.
For example, reviews of F. Scott Fitzgerald's The Great Gatsby that appeared in 1925 or 1926 (right after the novel was published) are book reviews, while literary criticism about the novel continues to be written today.
In addition, reviews are often meant to inform the potential reader about the content, quality, and usefulness of a book, whereas criticism is usually an academic study of a work.
