For nearly five decades, Choice's Outstanding Academic Title distinction has been a valued scholarly accolade. Books and electronic materials so honoured represent the best work reviewed in Choice over the course of a calendar year. Works that are selected as Outstanding Academic Titles, OATs, are distinguished by overall excellence in presentation and scholarship, importance relative to other literature in the field, and value to undergraduates. Titles may be selected because they are a first treatment in an evolving field of study or because they present an original or unique treatment in an established field. The OATs are the best of the best in scholarly publishing for undergraduates.
