In 1934, ICMA publishes its first edition of The Municipal Year Book, which sells 1,000 copies and quickly becomes the authoritative source for municipal data and information. ICMA staff member Herb Simon develops the Year Book’s classification of cities and presentation of statistical data that continued to be used through the 2010 edition. Introduction of the Year Book brought an end to publication of annual conference proceedings in a publication called the City Manager Yearbook.
