The AIM Editorial Board has developed evaluation criteria to identify the 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. * Approved Textbooks The list is organized by courses ranging from pre-calculus to upper division analysis and algebra. Each book has a brief description of its important features and information about how to get it. * Evaluation Criteria There are a number of features that the Editorial Board considers in evaluating textbooks. * Guide for Authors Here is some advice on questions facing open textbook authors. * Editorial Board The AIM Editorial Board develops the criteria for acceptance and reviews open textbooks. Open access curriculum material for inquiry based learning courses can be found at The Journal for Inquiry Based Learning in Mathematics.
