REPORT OF THE LIBRARIAN 



Dr. N. L. Brixton, Director-in-Chief. 



Sir: I have the honor to submit the following report for 

 the year 1909. 



A census of the library, taken at the end of the year, shows 

 21,708 bound volumes, an apparent increase of 478 volumes 

 since the last report. Successive censuses, being taken 

 directly from the books upon the shelves, at intervals of a 

 year, are liable to inconsistencies, owing to differences of 

 opinion as to exactly what constitutes a "bound volume"; 

 it is believed that a more conservative view of this question 

 has been taken this year than heretofore, which will account 

 at least in part for the small increase reported. 



Among the year's accessions were 345 volumes (many, 

 as usual, unbound); 152 pamphlets purchased on the ac- 

 count of the special book fund, and 61 volumes received 

 as gifts; the principal accessions have been listed from 

 time to time in the Journal of the Garden, as heretofore. 

 The number of volumes bound during the year is 353; of 

 these, 87 are the property of Columbia University, on 

 deposit at the Garden. At the time of writing this report 

 there are 234 volumes at the bindery; these have not been 

 included in the statistics of the library for 1909. 



The appended list shows the serial publications received 

 regularly by the Garden. 



Respectfully submitted, 



John Hendley Barnhart, 



Librarian.
