D u r i n g the symposium, the information 
needs of the scientific world, at least, were 
very clearly described, a n d a few of the 
imaginative methods which have been made 
by scientists a n d engineers to answer these 
needs were outlined. It is d o u b t f u l that the 
conference did much to end the Great 
Schism between the librarians, who under-
stand the m a g n i t u d e of the information 
storage a n d retrieval problem in its totality, 
a n d the p r o p o n e n t s of mechanization, who 
see only the failures of present systems in 
the highly specialized fields with which they 
are familiar. Dean Boaz a n d the library 
school of the University of Southern Cali-
fornia are to be commended on making a 
sincere effort to open channels of commu-
nication between the two viewpoints.—

Audio-Visual T o o l 
They See What You Mean. By [Eric F. Bur-

tis a n d James E. LeMay] Ozalid Audio-
Visual D e p a r t m e n t . J o h n s o n City, N. Y.: 
Ozalid Division of General Aniline and 
Film Corporation, 1959. 88p., $3.75. 

T h e overhead projector is an audio-visual 
tool that has a p p e a r e d since 1950 a n d made 
its presence felt q u i t e markedly in industrial 
audio-visual departments. It is beginning to 
a p p e a r at technical a n d academic meetings 
as an extension to the services offered by 
the older projection methods. It combines 
the freedom a n d spontaneity of the black-
board with the precision a n d artistry of the 
slide projector, while a d d i n g a n u m b e r of 
facilities not f o u n d in these standard tech-
niques. 

Ozalid does not make overhead projectors, 
b u t it does produce e q u i p m e n t a n d supplies 
used in p r e p a r i n g transparencies for these 
projectors. T h e bulk of this superbly illus-
trated volume deals with the preparation of 
transparencies by the diazo process. T h i s is 

to be expected as Ozalid is the outstanding 
producer of diazo materials in this country. 
Sections of the book are given to homemade 
transparencies, T r a n s f e r o n (diffusion-trans-
fer), transparency m o u n t i n g techniques, 
transparency design, a n d overhead projec-
tion techniques. Much of this m a n u a l could 
be used to improve presentations based on 
the blackboard a n d slide projector, and it 
will certainly add to the versatility of the 
d e p a r t m e n t using an overhead projector. 

T h e r e is a short bibliography at the end 
of the book referring the reader to sixteen 
recent reports on overhead projection. T h e r e 
is also a two-page listing of Ozalid audio-
visual products, which serves as a glossary 
to the many terms savoring of jargon that 
appear in the book. T h e illustrations with 
which the book is filled serve to simplify the 
description of techniques a n d exemplify the 
visual method at its best. T h e profusion of 
trade-names in the text tends to minimize 
the effectiveness of this portion of the book. 
The volume can be recommended for all li-

braries engaged in or about to become in-
volved in audio-visual work.—Hubbard W.

Soviet Publishing 
Publishing in the U.S.S.R. By Boris I. Go-

rokhoff. (Indiana University Publications. 
Slavic and East E u r o p e a n Series, Vol. 19.) 
[Bloomington, Ind.: I n d i a n a University, 
cl959.] xvi, 307 p. $3.00; cloth, $6.00. 

I n spite of the recent burgeoning of arti-
cles about Soviet methods of disseminating 
scientific information there has been a need 
for full length studies in English which 
would give a balanced presentation of Soviet 
libraries, bibliography, a n d publishing in 
general. T h e Council on Library Resources, 
Inc., has acted to fill this need by s u p p o r t i n g 
Paul Horecky's Libraries and Bibliographic 
Centers in the Soviet Union, Volume 16 in 
the I n d i a n a series, a n d its companion vol-
ume on publishing. T o g e t h e r they form a 
valuable survey of the current scene. T h e 
competence in research on Soviet Russia, 
built u p in large measure since W o r l d W a r 
II by the area institutes in American uni-
versities, appears to have been joined hap-
pily with experienced librarianship i n the 
production of these studies. A volume on
