REPORT OF THE LIBRARIAN. 9 



V. REPORT OF THE LIBRARIAN. 



The growth of the Library continues steadily. The number 

 of books added during the year was 473. Of these eighty vol- 

 umes were received by purchase, 199 by binding of periodicals, 

 157 were gifts, and 21 were additions to the permanent loan 

 from the American Museum of Natural History. Our valuable 

 collection of reprints has been increased by the addition of 

 434 pamphlets. 



The number of periodicals currently received was 229; of 

 which 87 are received by subscription, 59 by exchange for the 

 Biological Bulletin, 69 were gifts, and 14 were duplicates lent 

 to us by the American Museum of Natural History. The total 

 contents of the Library at the end of the year is 11,136 volumes 

 and 9,393 pamphlets. 



Two of the gifts received during the year are especially note- 

 worthy. The first to be mentioned is the gift from Mrs. George 

 Peirce of books selected from the working library of her hus- 

 band, a distinguished physiologist and chemist, whose herioc 

 death in 1919 at the height of a productive career of research 

 has retarded the advance of biochemistry in America. This is 

 a collection of thirty volumes, all recent books of importance, 

 and is a very valuable addition to our library. 



The second gift of special note is a complete set of the cards 

 of the Concilium Bibliographicum. This is given by the Library 

 of Carleton College through the good offices of Dr. Donnell B. 

 Young of our Instructing Staff. These cards will be of very 

 great use in the bibliographic research that is a prominent part 

 of the work of investigators every summer. But before they 

 can be used these cards must be filed in a suitable cabinet. 

 Until a cabinet and room for it can be provided, the cards can 

 only be stored. 



Another notable gift is a collection of thirteen volumes of 

 their publications given by Messrs. P. Blakiston's Son & Com- 

 pany through their representative, Mr. Horace G. White. These 

 books, with one exception, are all published in 1919, or later, 

 and all are desirable additions to the Library.
