While it has been the aim of the library to secure all of the books on forestry written in English, the bulk of the forest literature is still in German and French. The titles listed in this bulletin include all of the books and pamphlets on forestry in the department library, but no periodical articles unless reprinted in separate form. The present catalogue contains 4,001 entries. It includes all the books relating to forestry received by the library previous to January 1, 1912, but the entries for periodical and serial publications have been brought up only to the end of 1910.
