42 Report of the President 



The work of publicity, carried on as a branch of the Regis- 

 trar's duties, involved the preparation and distribution of 50 

 articles, which were circulated not only in the 

 United States but to some extent in Canada, Eng- 

 land and France. The regular mailing list now includes about 300 

 newspapers, magazines and special writers. The above does 

 not include information and illustrations given to individuals on 

 request. 



The sales of publications have continued to be good, and pre- 

 sumably show a demand on the part of the public for informa- 

 tion. Exclusive of "An Hour in the Museum," 

 Publication 1»551 copies of which were sold, the sales were 

 as follows: General Guide, 5,823; Handbooks, 

 1,617; Leaflets, 4,894; reprints, 724; a total of 13,058 copies, 

 1,371 more than in 1920. The sales would doubtless have been 

 larger had it been possible to keep all the publications in print, 

 larger still had it been possible to add to them, but the demands 

 on the printing force have far exceeded their possibilities in the 

 way of supply. The addition of Nozritates to the museum pub- 

 lications has, it is hoped, proved of service to the world of 

 science, but it has unavoidably prevented the issue of other 

 matter, so the end of the year sees one Handbook and four 

 Leaflets out of print, besides the General Guide, and the end of 

 several others in sight. 



The large sale of the Guide is due to the fact that for the first 

 time in ten years it has been possible to keep it continuously on 

 sale throughout the year, a condition that unfortunately can not 

 continue. The small sale of the Key is related to the large sale 

 of the Guide, and the drop in reprints comes from the fact that 

 some have been made Leaflets and others have gone out of print 

 Next, to the General Guide, by far the "best seller" was the 

 Guide Leaflet, "The Hall of the Age of Man," which established 

 a record with a sale of 1,119 copies in eight months. 



The output of the printing office shows its customary effi- 

 ciency in meeting the demands upon it, which, due to the 



. , establishment of Novitates and the meeting of the 



Plant Eugenics Congress, have been greater than ever.
