REPORT OF THE LIBRARIAN 
Dr. N. L. Britron, Drrectror-1n-CHIEF. 
Sir: I have the honor to submit the following report for 
the year 1916. 
According to a census of the library taken at the end of 
the year, the number of bound volumes was found to be 
27,039, an increase of 415 volumes since the report for 1915. 
During the year 266 books have been bound, including 
24 which are the property of Columbia Caney: while 74 
have been rebound. 
Among the accessions are 48 books acquired by purchase, 
and 70 by exchange and deposit. There have been 112 
gifts. Columbia University has permanently recalled 
39 of her books. 
The cataloguing is now kept practically up to date. 
There have been added to the catalogue during the past 
year 1,104 written and typewritten cards, in addition to the 
printed cards issued by the Torrey Botanical Club. A 
beginning has been made upon the revision of the catalogue. 
The work thus far done consists chiefly in the extension and 
correlation of the subject headings, together with the 
supplying of biographical data. Very much remains to be 
done. 
In the spring, a persistent effort was made to complete 
the files of Agricultural Experiment Station publications, 
with gratifying results in many cases, though some of the 
earlier numbers are still lacking. 
During the year the labels upon the books throughout 
the library have been renewed where necessary. 
In October there was made through the Department of 
State, and with the endorsement of the Librarian of 
Congress, an application for a permit for the shipment to the 
United States of certain of our periodicals which are de- 
tained at Rotterdam. The latest information from Wash- 
ington states that a representative of the Library of Con- 
gress will sail for Rotterdam early in January, and “will 
lend his good offices in securing prompt inspection of the
