Today we received an updated list of confirmed universities with courses using our book as a required text. As before, the list does not cover non-American universities, nor is it an exhaustive list. We were thrilled to discover continued strong growth. Last year at this time, the number of universities was 48, and this year the book has been adopted now at 90 universities in just the United States. An international version of the book is available outside the USA, but the publisher doesn’t know which universities outside the USA have adopted it.
