• A writer may purchase a manuscript record book or may prepare his own book or card index. 
• In fact, in most modern studios, an elaborate card index system of listing locations, sometimes situated miles from the studio, is maintained. 
• One of these cards indexes contains the names and titles of all the articles published in the society's annual reports and is indexed also with the names of the writers, the index being prepared in this double manner. 
• The society is maintaining its card indexes and adding year by year to the amount of material which they represent.
