The law of this free city decreeing that no Jew should establish a printing house there greatly impeded the development of Hebrew publishing in Frankfurt. Many books published there, especially prayer books, appeared without place of publication or publisher's name. Owing to this restriction, the printing requirements of Frankfurt were in large measure met by Jewish presses established in neighboring towns and villages, such as Hanau, Homburg, Offenbach, and Rödelheim, the last-named place being specially notable. Besides the local wants of Frankfurt there was the yearly fair which was practically the center of the German-Jewish book trade. In a measure the presses of the above four towns were really intended to supply the fair trade of Frankfurt.
