REPORT OF THE LIBRARIAN. 



To the Director-in-Chief : 



Dear Sir : I beg to submit the following report on the Li- 

 brary, covering the period from January i, 1901, to January 

 1, 1902 : 



The last census of the Library was taken on December 

 28th, and the number of bound volumes was then shown to 

 be 11,314, showing an increase for the year of 2,482 vol- 

 umes. Of these, 569 volumes were presented to the Garden, 

 825 volumes were purchased by the Special Book Fund and 

 256 volumes were deposited at the Garden by Columbia Uni- 

 versity, the remainder being acquired through subscription 

 or by exchange. 



The card catalogue of the books deposited at the Garden 

 by Columbia University in December, 1899, has been com- 

 pleted, and the entire collection of the books belonging to 

 the Garden has also been catalogued. 



The binding of the books and pamphlets belonging to both 

 institutions has progressed satisfactorily, and 973 volumes 

 have been bound during the year, of which 273 were serials 

 and pamphlets belonging to Columbia University. 



A most important addition to the Library is the collection 

 of books on paleobotany belonging to Columbia University, 

 which, according to an agreement, dated May 3, 1901, be- 

 tween the two institutions, was transferred to the Garden dur- 

 ing the month of November. It is temporarily installed in 

 the rotunda of the Library until suitable shelves can be built 

 for it, and consists of 200 volumes and some 300 unbound 

 pamphlets. 



Other valuable additions are a collection of books on the 

 Characeae, the gift of Dr. Timothy F. Allen, and of several 

 sets of serials, mainly on microscopy, the gift of the Rev. 

 Dr. Haslett McKim. 



Several important horticultural serials have been procured, 

 thus adding materially to the effectiveness of that depart-
