Several contributors have mentioned relatively late textbooks, such as Branson's, when Warren Young has already pointed out the example of Meade's 1936 textbook, which had a 1938 U.S. edition. If one wants a popular U.S. textbook, Hansen's "Monetary Theory and Fiscal Policy" (1949) gives an IS-LM analysis. Samuelson's "Economics," 3rd edition (1955) popularized the "Hicks-Hansen" IS-LM model, although he relegated it to an appendix. Kevin Hoover
