technicians, artists, and teachers, nor its influence throughout the world can
be estimated by a casual observer. Behind its exhibition halls are hundreds
of classrooms, laboratories, editorial offices, libraries, lecture halls, studios,
study collections, and files of vital data. And from the museum go ex-
plorers, educators, astronomers, and geologists to increase man's knowledge
of the external world and to help him win victories over his environment.

The fifth floor of the museum is given over to the administrative offices,
the scientific departments, and the library. The workrooms are used for
the preparation of fossils, models, and other exhibits. The main library
contains more than 117,000 volumes. A second library, founded by Henry
Fairfield Osborn, is devoted to vertebrate paleontology.

The museum issues technical publications on its researches and expedi-
tions, and on timely discoveries and theoretical questions. Its popular pub-
lications include the general guide, school service series, the journals Nat-
ural History and Junior Natural History, guide leaflets on the collections,
and a number of handbooks which may be used as textbooks on subjects
illustrated by collections in the museum.

Enormous study collections of hundreds of thousands of specimens in
all branches of the natural sciences are available to students and research
workers. An idea of their extent may be had from the fact that the insect
collection alone consists of more than one million specimens; that of fishes,
10,000; of birds, 750,000, the largest in the world; of fossil mammals,
30,000 catalogued, and of fossil invertebrates, 700,000 specimens cata-
logued. A fully equipped printing plant is constantly employed.

Lastly, and of tremendous importance, are the educational services of the
museum in the form of lectures to children in the public and high schools
and to students in colleges and universities, classes and guide services,
sponsorship of scientific societies, motion-picture and lantern slide services,
circulating collections, radio broadcasts, and nature hikes. The number of
people affected by these activities reaches in one year the almost incredible
number of 43,000,000.
