36 MISSOURI BOTANICAL GARDEN. 
The additions for the year number 829 books, valued at 
$1,280.50, and 3,859 pamphlets, valued at $523.15, pre- 
sented or received in return for Garden publications; and 
475 books and 219 pamphlets bought, the expenditure for 
purchases and binding amounting to $1,577.14. 
The card index has been enlarged by the addition of 
97,676 cards, of which 79,039 were written by employees ; 
16,146 were purchased; and 2,491 were presented. Among 
the additions are many cards referring to floral ecology 
and to seedlings, the former subject being now represented 
by some 33,000, and the latter by about 28,000 cards, 
while the references to plant illustrations number about 
190,000. 
The distinct serial publications now received at the 
library number 1,237, of which 93 are bought and 1,144, 
issued by 859 institutions or publishers, are received in 
exchange for the Reports of the Garden. The total here 
reported is 13 smaller than that reported for 1904, as the 
result of a careful revision to date, —a considerable num- 
ber of publications having been discontinued, although a 
number of additions have been made to the exchange list.*

During the year just closed, a special provision by the 
Board has enabled the librarian to begin the preparation 
of alist of biological serials contained in the libraries of 
St. Louis. Satisfactory progress has been made on the 
manuscript of this list, which is expected to be completed
