cut off almost completely the trade with the book markets 
of those countries, and the offerings from old libraries in 
other European countries have continued unimportant to us. 
Reclassification of Books.—The books and pamphlets 
bearing on the fungi are arranged alphabetically under au- 
thor, a simple arrangement which has proved very satisfac- 
tory for finding quickly any publication in this section pro- 
vided the author is known, but it has been of no aid in show- 
ing all the resources at hand in any subject subdivision of 
mycology. In order that no work may be overlooked, a sub- 
ject card index has been in course of preparation during the 
year, and approximately 2,700 cards have been prepared 
already. Such a subject index for the portions of our library 
in most constant use has been greatly needed. It requires 
for its preparation only a fraction of the labor by the library 
staff which a reclassification of the books would have in- 
volved, and no user of the library has been inconvenienced 
by the work in progress. At any time in the future when 
different ideas in mycology may prevail, these cards may be 
rearranged under a new set of subject guides to be of the 
utmost service again. 
Publications. — The ANNALS OF THE Missourt BoTANICAL 
GARDEN is our principal exchange for publications of scien- 
tific institutions and societies. The current volume of 512 
pages, 9 plates, and 84 text figures contains the results of 
otanical researches by individuals connected with the Gar- 
den. It is computed that the value per year of exchanges 
received for the ANNALS is about $1,500.00. Some exchanges 
are also received for the BuLteTiIn. Both the ANNALS and 
the BuLLETin are supplied to regular subscribers, and sepa- 
rates of the various articles in the ANNALS are for sale by the 
library. The cash receipts from subscriptions and separates 
for the year were $331.64, 
Loans of Books. — Inter-library loans of many books 
which are needed by investigators in educational institutions 
have been available. The borrower makes application for 
the loan ae the library of his home university, which 
1s responsible for its return at the expiration of the term 
and the age of transportation both ways. Loans total- 
ing 118 books have been made to 25 libraries in all parts of 
the middle west, chiefly during the year. 
Card Index to Mycological Exsiccati.— The old card in- 
dex to the contents of the mycological exsiccati was eumber- 
some by giving one card to each specimen, and the matter 
for which one consulted the card was inconveniently written 
at the very bottom. During the present year the library
