REPORT OF THE LIBRARIAN 
To THE DirecToR-IN-CHIEF. 
Str: I have the honor to submit the following report on the 
Library, covering the period from January 1, 1906, to Jan- 
uary I, 1907. 
A census of the Library was taken December 17, and the 
number of bound volumes was then found to be 19,984 with 
378 volumes in the bindery, making a total of 20,362 vol- 
umes, showing an increase for the year of 2,733 volumes. 
Of these, 1,057 were purchased from the special book fund, 
184 volumes were presented to the Garden, the remainder 
having been acquired by subscription and exchange or by 
deposit from other institutions. Of those purchased from the 
special book fund, 832 titles, amounting to 918 volumes and 
pamphlets, were obtained through the special arrangement 
made by yourself with a firm in Europe in 1905 for the acqui- 
sition by the Garden of the works of the older botanical 
writers. This has resulted in the addition to the Library of 
a number of valuable works. No estimate has been made of 
the number of unbound pamphlets. 
During the year 757 volumes have been bound, of which 
84 volumes are serials and pamphlets deposited at the Garden 
by Columbia University. 
The card-catalogue has been kept up to date; about 4,900 
written cards having been added to it. 
Additional exchanges have been arranged with other insti- 
tutions, and the number of journals, periodicals, reports and 
other publications now received in that way in exchange for 
Garden publications, or by subscription, is about 570 as 
against 500 during 1905. 
Accessions to the Library, other than serials and regular 
exchanges, have been published monthly in the JourNAL. 
The rearrangement in 1905 of the steel book-stacks has 
proven satisfactory, and 75 steel shelves have been provided 
this year, furnishing considerable additional space.
