REPORT OF THE LIBRARIAN 
To THE DirEecTOR-IN-CHIEF: 
Str: I have the honor to submit the following report on 
the Library for the year 1907. 
Upon my appointment as Librarian in October, I found the 
library in excellent condition in every respect; this reflected 
much credit not only upon my predecessor, but upon those 
who had the care of the Library during her absence in 
Europe for the five months immediately preceding my ap- 
pointment. 
According to a census of the Library, it contained at the 
end of the year 20,458 bound volumes, an apparent increase 
of only 96 volumes from the number stated in last year’s 
report. This has necessitated a careful review of the statis- 
tics of the Library for the past few years, and a comparison 
of the recorded additions during 1906 with the figures shown 
by the census taken at the end of that year; the result has 
convinced me that last year’s report contained a clerical error, 
by which the number of volumes was stated at 20,362 when 
it should have been 19,362. In this case, the actual increase 
shown by this year’s census is 1096 volumes, and this prob- 
ably approximates the actual number of additions. As in 
former years, no estimate has been made of the number of 
unbound pamphlets; nearly all of these, however, are in 
temporary covers, shelved, and catalogued, so that they may 
be consulted as conveniently as the bound volumes. The 
accessions during the year include 516 volumes purchased on 
the account of the special book fund, and 76 presented to the 
Garden. 
During the year 704 volumes have been bound; of this 
number 52 were the property of Columbia University, on 
deposit at the Garden. 
The additions to the catalogue have included about 3700 
written cards. By this means the increase of the catalogue 
has kept pace with the growth of the Library; but although
