Among the criteria for inclusion is that they must be used in higher education teaching or be associated with a higher education institution. Textbooks in economics can be found under "Browse Subjects" either under "Business" for business textbooks or "Social Sciences" &gt; "Economics" for economics textbooks. Alternatively, you can also use the search function to search specifically for textbooks on topics such as "Statistics" or "Macroeconomics". The Open Textbook Library is supported by the Open Education Network.
