Consumers can purchase teacher's editions of textbooks online through sites such as Amazon.com, AbeBooks.com, eBay.com, Biblio.com and TeacherEditions4Less.com, as of April 2015. Buyers purchasing a teacher's edition to match a specific set of student textbooks should check the publishing edition to ensure that both are from the same set.
A teacher's edition of a textbook covers the same information as the student edition, but includes additional information about certain aspects of the material and guides for creating tests. The information included varies based on the subject. For example, a teacher's edition of a math textbook typically contains answers to the problems included in each section.
