To Speakers at Cincinnati Meetings; A.A.A.S.: 
The Association will conduct a publicity service for the approaching 
meetings of the American Association for the Advancement of Science, affil¬ 
iated and associated societies at Cincinnati, December 27 to January 3 , As 
far as possible, this service will furnish tne daily press with authentic 
material regarding the meeting and the papers and addresses there given. 
A copy or complete summary of the paper or papers that you are to pre¬ 
sent is needed in advance of the meeting. Please mail at once in the enclosed 
envelope to Science Service, using the accompanying blue sheet; 
Two copies of your paper, or 
Two copies of a summary of your paper, putting in non-technical 
language the points of most importance and popular interest.

Science Service is lending very valuable aid to the Association in this 
publicity work. The service is an endowed institution established at Washing¬ 
ton for the purpose of popularizing scientific knowledge. The Association ap¬ 
points representatives in the board of trustees of Science Service, thus taking 
part in its control, and a majority of the members of the board are members of 
the Association. In preparing its Daily Science News Bulletin, sent regularly 
to a number of subscribing newspapers, Science Service will make use of the ma¬ 
terial received, and this will also be made available, through the Association's 
Publicity Committee, at the University of Cincinnati, for the general use of 
the press, The Bulletin, as well as matter given out by the Publicity Committee, 
will be released only at the proper time. 
One of the most difficult features of our meetings has to do with proper 
publicity, and I wish especially to ask you and to urge you to do your part 
promptly, to the end that our publicity work at Cincinnati may be efficient, 
comprehensive and satisfactory.
