THE JOSSELYN VAN TYNE MEMORIAL LIBRARY 
The Josselyn Van Tyne Memorial Library of the Wilson Ornithological Society, housed in the University of 
Michigan Museum of Zoology, was established in concurrence with the University of Michigan in 1930. Until 
1947 the Library was maintained entirely by gifts and bequests of books, reprints, and ornithological magazines 
from members and friends of the Society. Two members have generously established a fund for the purchase 
of new books; members and friends are invited to maintain the fund by regular contribution. The fund is administered 
by the Library Committee. Jerome A. Jackson, Florida Gulf Coast Univeristy. is Chairman of the Committee. The 
Library currently receives over 200 periodicals as gifts and in exchange for The Wilson Journal of Ornithology. For 
information on the Library and our holdings, see the Society's web page at http://www.wilsonsociety.ori:. With the 
usual exception of rare books, any item in the Library may be borrowed by members of the Society and w ill be sent 
prepaid (by the University of Michigan) to any address in the United States, its possessions, or Canada. Return 
postage is paid by the borrower. Inquiries and requests by borrowers, as well as gifts of books, pamphlets. repnnLs. 
and magazines, should be addressed to: Josselyn Van Tyne Memorial Library. Museum of Zoology. The University
