Excerpt from Iowa Authors and Their Works a Contribution Toward a Bibliography The idea of such a list is not new. It remained, however, for Miss Marple to engage in its present exhaustive character. She has availed herself of the following aids: A list prepared by the late Hon. Theodore S. Parvin; a partial chronological list kindly loaned by Professor Selden L. Whitcomb, now of the University of Kansas; a list prepared by the Iowa Press and Authors Club; Some Recent Publications by Iowa Authors, current in the Iowa Journal of History and Politics; A list of books by Iowa Authors, by the Iowa Library Commission, 1904; the excellent collection of clippings upon, and of volumes by Iowa authors in the Iowa State Library. But her greatest aid was the books and pamphlets in the Historical Department itself, of which the collections of the Louis iana Purchase Commission, and the collection of Hon. Henry Stivers, of Osceola, Iowa, lately acquired, form a large portion. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

A timeless classic of economic theory that remains fascinating and pertinent today, this is Frank Knight's famous explanation of why perfect competition cannot eliminate profits, the important differences between "risk" and "uncertainty," and the vital role of the entrepreneur in profitmaking. Based on Knight's PhD dissertation, this 1921 work, balancing theory with fact to come to stunning insights, is a distinct pleasure to read. FRANK H. KNIGHT (1885-1972) is considered by some the greatest American scholar of economics of the 20th century. An economics professor at the University of Chicago from 1927 until 1955, he was one of the founders of the Chicago school of economics, which influenced Milton Friedman and George Stigler.
