Each paper accepted for publication in one of the above periodicals is accompanied by the 

 author's abstract (not exceeding 250 words) and a list of subject headings under which the various 

 sections of the work are treated. 



Upon receipt at The Wistar Institute, the abstract is printed immediately on one side of a 

 standard library card. On the reverse side of the card is given the complete bibliographic refer- 

 ence to the paper as it will appear eventually, the various subject headings following the main 

 title. Copies of this abstract bibhographic card are distributed at once to the anatomists, zool- 

 ogists, university and college hbraries, research institutes, public libraries, academies and scien- 

 tific societies of the world. 



This instant publication of results precedes the appearance of the full teft of the paper in a 

 journal by some weeks and in some instances by months. The abstracts;' are translated into 

 the Spanish, Japanese and Chinese languages and are priuted in these languages together with 

 the fuU English text, in the Spanish, Japanese and Chinese editions of the several journals pub- 

 lished by The Wistar Institute. 



For the Author: The Bibliographic Service gives immediate publicity to his investigations, 

 places the reference to his work on file in the important public and private libraries and makes 

 his writings easily available to all groups of readers. 



For the Investigator: The Bibhographic Service brings the essential features of the latest re- 

 searches promptly to his attention with the least expenditiu:e of time and makes it possible for 

 him to select quickly the papers which he wishes to read in detail. 



For the Teacher: The abstract reference cards make it easy for him to keep informed 

 upon the progress of his science from day to day without the necessity of an orgy of reading 

 at more or less long intervals at the university hbrary. 



For the Student: No better stimulus to activity is offered than a glimpse at the progress being 

 made in anatomy and zoology. 



For the Librarian : This service makes it possible to classify and catalogue technical papers in 

 anatomy and zoology according to author, title, and subject headings with a minimum of effort 

 and without the necessity of reading the complete papers. 



Subscribers to this service receive two cards for each publication; one bearing the abstract 

 on one side with the reference on the reverse side (main entry card to be filed alphabetically 

 according to author), the other bearing the reference only and intended to be used as a subject 

 index card. Extra cards may be secured. 



The subscription price is $5.00, for the year ending June 1, 1921. Cards already issued 

 will be supplied.
