REPORT OF THE BIBLIOGRAPHER 
Dr. N. L. Brirron, Drrector-1n-Culer. 
Sir: I have the honor to submit the following report for 
the year 1917. 
The usual bibliographic study, correspondence, and 
library assistance have been continued throughout the 
year. The development of the library has been chiefly by 
gifts and exchanges, little money being available for the 
purchase of books. 
Only 3 parts of North American Flora have been issued 
during the year: Volume 10, Part 2, in April, and Volume 
21, Part 2, and Volume to, Part 3, in June. Volume 21, 
Part 3, is nearly ready to appear. More manuscript is in 
hand and in sight than at any time before, and it is hoped 
that 1918 may be a record year in the progress of the Flora. 
The second volume of Addisonia has been completed, in 
four parts of ten plates each. 
Historical studies have consumed rather more of the 
Bibliographer’s time this year than usual. In May, at 
the Centennial Meeting of the New York Academy of 
Sciences, he presented a historical sketch of the Academy; 
this was published in the Scientific Monthly for November. 
In October the Torrey Botanical Club celebrated its semi- 
centennial with a series of meetings, which opened with a 
sketch of the history of the Club by the same writer. Both 
historical sketches were brief, but no little study was neces- 
sary to insure their accuracy. A series of biographical 
notes on the botanists of Charleston, South Carolina, 
appeared in the Garden Journal for November; and a list 
of authors, upon a scale never before attempted in a work 
of this kind, was prepared for Rydberg’s “‘Flora of the 
Rocky Mountains,” which appeared on the last day of the 
year. 
Respectfully submitted, 
Joun Henptey Barnuart, 
Bibliographer.
