THIRTY-FIFTTT BIENNIAL REPORT 27 



portion of the librarian 's time is spent in hunting references and giving 

 other assistance. 



The library, with its limited Imdget, depends to a large extent for 

 its growth on its exchanges and gifts with and from other scientific 

 and educational institutions. It is a pleasure to note that of the 483 

 bound volumes acquired during this period, 202 represent gifts. Like- 

 wise of the 140 periodicals regularly received, 102 are on the exchange 

 or free basis. 



The record of bound volumes at the end of this period number 

 2250, with a valuation of $8,004.48. Scientifie and other pamphlets on 

 record number 5657, with a value of $908.79. Of these 770 were 

 received during this period. 



Consideralile binding of back issues of periodicals was continued 

 under a WPA project, which unfortunately, due to a governmental 

 ruling on one-man projects, was terminated April, 1938. A large 

 amount of binding still remains to be done, and hundreds of pamphlets 

 are yet to be accessioned and made available. 



Through the listing of the library's periodical inventory with the 

 San Francisco Special Libraries Association and embodying same in 

 the pu])lication "Union List of Periodicals," more people are learning 

 that the Division's library has material not to be found elsewhere 

 in this bay area, and consequently many requests are being made for 

 reference to such material. Students of universities and schools con- 

 tinue to use our facilities. 



We are grateful to the libraries of the California Academy of 

 Sciences, University of California, United States Forest Service, and 

 our own Terminal Island office for the kind assistance given in lending 

 to us literature, which we already possess, however, but which is not 

 easily available while in storage. 



Your Executive Officer desires to express his sincere appreciation 

 and that of the entire personnel of the Division for the firm, fair and 

 kindly treatment and assistance that your honorable board has ren- 

 dered us during this two-year period. 



Respectfully submitted. 



Herbert C. Davis, 



Executive Officer.
