The publication of a monthly paper was started in 1902 as a means of communication with the general public and especially with schools. In April, 1905, the Children's Museum united with the larger Museum of the Brooklyn Institute of Arts and Sciences, in publishing the Museum News. This journal is sent not only to every public and private school in Brooklyn, but to every museum in this country and abroad; to every library in Brooklyn, and to libraries generally throughout the country. An excellent "Guide to the trees in Bedford Park" has been printed in a separate leaflet, being at first a contribution to the Museum News. It may be noted here that a series of lectures upon Trees will be given at the Children's museum commencing April 11th by Mr. J. J. Levison, arboriculturist, the author of the "Guide"; and that a fine collection of the best tree books may always be consulted in the library. In connection with the "Hudson-Fulton Celebration" in the fall of 1909, a handsome "Catalogue of the historical collection and objects of related interest at the Children's Museum" was prepared by Miss Agnes E. Bowen. It furnishes a concise outline of American history, is printed in attractive form, and illustrated by photographs of the historical groups already mentioned. Special picture bulletins were also exhibited in both museum and library, and objects having relation to Hudson and Fulton and their times were indicated by a neat little flag. It is perhaps needless to add that many teachers and children found great assistance by consulting the "Hudson-Fulton Bookshelf," and that the museum exhibit was very attractive to the general public. The library has prepared various short lists from time to time whenever needed, but has thus far printed only one. This was prepared at the request of the Supervisor of Nature Study in the Vacation Schools of Greater New York, and is a short annotated list entitled "Some books upon nature study in the Children's Museum Library." The list will be sent free to any librarian or teacher upon application. The Children's Museum is open daily throughout the year, the hours on weekdays being from 9 a.m. to 5:30 p.m., and from 2 to 5:30 p.m. on Sundays. The library is open on the same hours as the museum with few exceptions, such as Thanksgiving Day, Christmas, and the Fourth of July, and Sunday afternoons during the summer, from June 15th to September 15th.
