REPORT OF THE LIBRARIAN. 

 To the Director-in-Chief : 



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

 Library, covering the period from January i, 1900, to Janu- 

 ary 1, 1901 : 



The botanical library of Columbia University, which was 

 moved on the last days of December, 1899, has been com- 

 pletely shelved and the books have been sorted and classified 

 with those acquired by the Garden since 1896, so that both 

 libraries are arranged in one series, each volume, however, 

 being bookplated so as to be distinguishable. The books 

 were counted as soon as shelved and on February 1st, the 

 bound volumes numbered 7,117 with some 300 volumes at the 

 bindery. Of the vast amount of pamphlet literature, no ac- 

 count was taken. The last census of the books was taken 

 on December 29, 1900, show the numbering then to be 

 8,832: the increase for the year being 1,415 volumes. Of 

 these, 639 numbers, some of them pamphlets and separates, 

 were purchased by the Special Book Fund, the remainder 

 being acquired by gift or exchange. 



The volumes for 1899 of the serial publications deposited 

 by Columbia University have been bound by the University 

 as far as they have been completed, and the Garden has 

 begun to bind these for 1900, in accordance with an agree- 

 ment between the two institutions. 



The loose pamphlets and separates belonging to Columbia 

 University have been sorted and classified and 9 volumes of 

 them as well as a number of single separates have been 

 bound. It is planned to have them all bound ultimately, no 

 matter how small and insignificant. 



A copyist has been steadily at work for two months, dupli- 

 cating the card catalogue of the books deposited by Columbia 

 University and about one-third of the catalogue is ready for use 

 and more than one-half of the books belonging to the Garden 

 are catalogued. A shelf list of the entire Library also has
