INFORMATION FOR SUBSCRIBERS 



T 



WO THOUSAND SERIAL PUBLICATIONS ARE BEING 

 CONSULTED TO SECURE ABSTRACTS AND CITA- 

 TIONS FOR BOTANICAL ABSTRACTS. 



The Bibliographical Committee anticipates that this reference 

 list will be increased to twenty-five hundred publications before the 

 end of 1920. 



The large number of references available is amazing even to 

 those who felt that they possessed a comprehensive knowledge of the 

 available literature. 



Anyone who is seriously interested in plants ought to want Bo- 

 tanical Abstracts as his own property, just as he wants certain books 

 in his own library. Every day we receive further assurances from 

 subscribers that the}' regard Botanical Abstracts as a most important 

 necessity 



It is regretted that Volumes I and II are no longer available. 



The first two issues of Vol. Ill (the two volumes for 1920 are 

 to be Vols. Ill and IV) are available and will be promptly sent to 

 3'ou on the receipt of your order. A statement will be rendered at 

 anytime w T ithin ninety days if you prefer. Just don't delay, but 

 order at once, is the best suggestion we feel could be made.
