classifying the section of monographs of Systematic Botany. A 
member of the scientific staff assisted in assigning family names, 
and the changing of numbers on cards and books of the entire 
group has been completed. 
9. Assistance was given in the making of various bibliographies 
during the year. Material was assembled, from other libraries as 
well as our own, checked and summarized, for a paper by the 
Director on the effect of radium rays on plants (a resumé of . . 
papers from 1901 to 1932), for a lecture on botanical literature, 
given by him before the New York Library Club; for an article 
on roses, rose culture, and rose gardens, which the horticulturist 
planned as a number of the Brooklyn Botanic Garden Recorp 
— 
(not yet published), and for one on plant propagation, published 
in Brooklyn Botanic Garden Leaficis, Ser. 21, No. 2-6, April 26, 
1933. A long list, prepared by the Metropolitan Museum of Art, 
on the literature of sources for botanical illustration, was checked 
and our holdings added, in connection with an exhibit at the Mu- 
seum of plant forms in ornament. 
10. Books, illustrations, seed catalogues, ete., were laid out 
for inspection on the special flower days observed by the Garden; 
and for a meeting of the executives of the Garden Club of America 
we exhibited a small group of books showing the development and 
history of botanical illustration. 
REFERENCE Work 
During the year we answered over five hundred reference ques- 
tions (ie. questions which required checking and searching for 
material) by mail and personally from members of the Garden and 
others who wished information on many aspects of botanical and 
horticultural science. Students of all ages came to prepare assign- 
ormation and material for lectures, 
ments, teachers to obtain in 
amateur gardeners for advice on the planting and care of flowers, 
the staff for lists of books, illustrations, identification of plants, 
— 
and elusive citations. It should be noted that all projects, prac- 
tical, educational, and scientific, planned by any department of the 
Botanic Garden, eventually require research work in the library, 
reviewing existing literature of the subject. Thus the library be- 
comes increasingly useful with each new development.
