Quadrangle Books, Inc. New Publishing Firm, PW, June 1, 1959, at 32:
Alexander J. Morin has left his position as managing editor of the University of Chicago Press to become the president of a new publishing company, Quadrangle Books, Inc., which will publish general nonfiction and reference books. Michael Braude, a Chicago businessman and writer, is the vice-president of the new firm, and Jeremiah Kaplan, who is also managing director of the Free Press of Glencoe, Illinois, is the treasurer.
Quadrangle Books’ list will include titles intended mainly for specialized audiences— libraries, scholars, collectors, and other specialists in a wide variety of fields. The initial titles will probably be entirely casebound, but later on the firm may go into the paperback field, again with a rather specialized list of titles.
