284 TWENTY-FOURTH REPORT. 



tions received from various members of the laboratory, especially 

 Dr. Pond, Dr. Osterhout, and Dr. Franklin. 



During the winter preceding the opening of the laboratory the 

 Assistant Librarian rearranged the books in the Library, placing 

 them in three series. Ordinary books are arranged at the west 

 end of the Library and placed in order according to the Dewey 

 decimal classification, the classification being somewhat minute 

 with a view to future expansion. The journals are arranged in 

 the next section of the Library and classified into a few broad 

 classes. Under each class the journals are arranged alphabetically 

 by title. The reprints are massed at the east end of the Library 

 and are all arranged alphabetically. We have been able to com- 

 plete ten important sets of journals by purchase, exchange, or 

 gifts. Among the important ones that have been completed are 



Morphologisches Jahrbuch, 

 Quarterly Journal of Microscopic Science, 

 The New Phytologist, 

 La Cellule, 

 Proceedings of the Boston Society of Natural History. 



The dictionary catalogue, which was started last year, now con- 

 tains 8,637 cards. The use of the Library has increased consider- 

 ably, the circulation for the year 1921 being 1,200 items. The 

 new forms which have been devised for keeping records have 

 proved very satisfactory and useful. 



The needs of the Library are numerous and various. We may 

 mention especially (i) reprints, of which none have been received 

 recently from members of the laboratory. Authors are requested 

 to look over the reprints in the Library when visiting Wood's Hole 

 and to send us what are lacking; (2) larger appropriations are 

 needed for the purchase of books much in demand; (3) special 

 needs are a good encyclopedia, bibliographical aids, such as the 

 Zoological Record after 1893, the International Catalogue sections 

 on botany, physiology, etc., from the beginning, The Royal Society 

 Catalogue of Scientific Papers; and, finally, much more room is 

 needed for the growth of the Library, and we are looking forward 

 to this need being satisfied in the near future. 



R. P. BIGELOW, 



Librarian.
