Now listed with the American Institute of Mathematics

Applied Discrete Structures is now listed among the Approved Textbooks by the American Institute of Mathematics as part of their Open Textbook Initiative.

The American Institute of Mathematics (AIM) seeks to encourage the adoption of open source mathematics textbooks. The AIM Editorial Board has developed evaluation criteria to identify open source books that are suitable for use in traditional university courses. The Editorial Board maintains a list of Approved Textbooks which have been judged to meet these criteria.

If you're looking for a text for a college/university mathematics course, consider books on this list!
