Excerpt from The Birds of Northern ThailandThe scientific publications of the National Museum include two series, known, respectively, as Proceedings and Bulletin.The Proceedings series, begun in 1878, is intended primarily as a medium for the publication of original papers, based on the collee tions of the National Museum, that set forth newly acquired facts in biology, anthropology, and geology, with descriptions of new forms and revisions of limited groups. Copies of each paper, in pamphlet form, are distributed as published to libraries and seien tific organizations and to specialists and others interested in the different subjects. The dates at which these separate papers are published are recorded in the table of contents of each of the volumes.The series of Bulletins, the first of which was issued in 1875, con tains separate publications comprising monographs of large zoologi cal groups and other general systematic treatises (occasionally in several volumes), faunal works, reports of expeditions, catalogs of type specimens, special collections, and other material of similar nature. The majority of the volumes are Octavo in size, but a quarto size has been adopted in a few instances in which large plates were regarded as indispensable. In the Bulletin series appear volumes under the heading Contributions from the United States National Herbarium, in octavo form, published by the National Museum since 1902, which contain papers relating to the botanical collections of the Museum.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
