In recent years, a growing number of universities support open access textbook initiatives aimed at lowering the education costs of social sciences students, such as in the field of economics. Thus, the OpenStax initiative of Rice University has supported the development of open access textbooks for both the Introduction into Economics courses and for more focused Principles of Macro-Economics and Micro-Economics courses. These courses are available both in web-based versions and as PDF-files. In addition to these materials, instructors can access course materials that can be used for graded quizzes and final exams. The macro- and micro-economics text books exist in editions that are oriented at both college-level students and high school students taking advanced-placement courses.
