It depends on the book's publisher. Some publishers peer review book proposals or book manuscripts before they are published. Such publishers include
- Cambridge University Press
- Oxford University Press
- Princeton University Press
- Routledge
- University of British Columbia Press
A book's author(s) may thank reviewers in an acknowledgements statement. Otherwise, a book does not include a statement that it was peer reviewed. To determine whether or not a book was peer reviewed it is necessary to consult a publisher's editorial policy to determine whether it peer reviews its publications.
