Money and Banking
This is a free, online textbook that can be downloaded as a pdf or customized. According to the authors, "Minimal mathematics, accessible language, and a student-oriented tone ease readers into complex subjects like money, interest rates, banking, asymmetric information, financial crises and regulation, monetary policy, monetary theory, and other standard topics. Numerous short cases, called "Stop and Think" boxes, promote internalization over memorization. Exercise drills ensure basic skills competency where appropriate. Short, snappy sections that begin with a framing question enhance readability and encourage assignment completion."
