Works copyrighted before 1964 had to have the copyright renewed sometime in the 28th year. If the copyright was not renewed, the work is in the public domain. No renewal notice was found for this periodical for issues published in this year. For instance, the first New York Times issue renewed was from April 1, 1928. Some publications may have renewed an individual article from an earlier time, for instance the New York Times renewed at least one article published on January 9, 1927. If you find any contrary evidence, or the renewal database has been updated, please notify me.
