MISSOURI BOTANICAL GARDEN BULLETIN 25 
LIBRARY 
During the year a considerable part of the time of the 
library staff has been devoted to checking up and entering 
the publications which have been received, sending them at 
once on the round of the laboratories, collating them for the 
ed: and finally indexing and distributing them on the 
shelves. 
There have been but few opportunities to purchase books 
which will fill gaps in incomplete sets, for the catalogues 
coming from foreign dealers appear to be almost wholly re- 
offerings of works in former catalogues. Private libraries are 
apparently not now being taken by foreign dealers. 
Reclassification of Books—To make the books and pam- 
phlets bearing on plant physiology and plant pathology more 
available for quick reference, there have been reclassified 
under the present subdivisions of physiology all the publi- 
cations in this section, as well as the books and pamphlets 
of importance in plant pathology from the section mycology. 
These changes have necessitated alterations in the corre- 
sponding cards in the card hg es and also in the original 
accession slips stored in the vault. This part of the work 
is not yet finished. 
Publications—The current volume of the Annals of 
the Missouri Botanical Garden, which is the principal 
exchange for publications of scientific institutions and 
societies, contains 841 pages, 27 plates, and 79 text figures. 
It contains the papers prepared for the Twenty-fifth Anni- 
versary of the Garden and also the results of botanical re- 
searches completed by individuals connected with the Gar- 
den. It is computed that the value per year of the exchanges 
received for the ANNALS is $1,335.00. Some exchanges are 
also received for the BULLETIN. 
List of Serial Publications.—The list of the serial publi- 
cations to date in the library of the Missouri Botanical Gar- 
den was published in the Washington University Serial List, 
Washington University Record, Vol. 10, No. 6, April, 1915. 
This list gives not only all serials in our library, but states 
also how complete the file is for each. In addition to being 
useful for our own use, this list will enable those who desire 
to consult volumes of such serials to inform themselves as to 
whether they are available in the Garden library. We have 
had in the past many inquiries of this nature from educa- 
tional institutions of the middle west.
