M. DEWEY:  Decimal Classification

Using Periodicals.  In the section on taking notes the direction was given that in citing legal decisions the latest should be secured.  Why?  That same principle applies to citing any kind of information in a speech.  Science, history, politics, government, international questions, change so rapidly in these times that the fact of yesterday is the fiction of today, and vice versa. A speaker must be up to date in his knowledge.  This he can be only by consulting current periodicals.  He cannot read them all so he must use the aids provided for him.  The best of these is the Reader’s Guide to Periodical Literature issued every month and kept in the reference room of all libraries.  In it, arranged under both subject and author’s name, are listed the articles which have appeared in the various magazines.  The December issue contains the entries for the entire year.  A group of topics from a recent monthly issue will show its value to the speaker securing material.

Eastern Question.  British case in the East.  H. Sidebotham, Asia 19:261-1263 Mr ’19.—­England and her eastern policy.  H. Sidebotham.  Asia, 19:158-161.  F ’19.—­Khanates of the Middle East.  Ikbal Ali Shah.  Contemp. 115:183-187 F ’19.—­More secret treaties in the Near East.  L. Stoddard.  Maps.  World’s Work. 37:  589-591.  Mr ’19.—­Part of the United States in the Near East.  R of Rs 59:305-306 Mr ’19.—­Should America act as trustee of the Near East?  Asia, 19:141-144 F’19.

By this time the student speaker will have that mental alertness referred to early in this book.  He will be reading regularly some magazine—­not to pass the time pleasantly—­but to keep himself posted on current topics and questions of general interest, in which the articles will direct him to other periodicals for fuller treatment of the material he is gathering.  The nature of some of these is suggested here.
