ENCYCLOPAEDIA BRITANNICA Office of the Editor: 20 NORTH WACKER DRIVE CHICAGO 6 October 11 1944 Mr. Ludwigh Von Mises 777 West End Avenue New York, New York Dear Mr. Von Mises: Mr. Yust is happy to learn that you will be in a position to revise or rewrite the articles BOEHM VON BAWERK, EUGEN (140 words) and WIESER, FRIEDRICH VON (70 words) for a forthcoming printing of the Encyclopaedia Britannica. He has turned the matter over to me to handle. I am enclosing pasted-up proofs of the articles as they now appear. Cor- rections should be made on the paste-ups themselves, and all deleted mate- rial should be clearly marked. If the article is to be rewritten entirely, salvaging none of the old material, cross out the entire paste-up and at- tach your new manuscript to it. In any event, please be sure to return the pasted-up proofs. You may feel free to revise or rewrite as much as you, in your good judgment, think necessary. We ask, however, that you keep within the present space limitations, Also enclosed is a copy of our "Encyclopaedia Britannica Contributors' Guide" to help you in the preparation of your material. A shorter list of directions is attached. I shall look forward to receiving copy from you by January 1. Sincerely yours, Haward Karch To All Britannica Contributors: Howard E. Kasch In writing articles for all Britannica publications, it is impor- Assistant to the Editor tant to avoid use of the present and simple future tenses, unless you find it absolutely impossible to do so. Use instead the past tense and date the event or development of which you write. Also avoid such words and phrases as "recent," "now," "25 HEK:bp years ago," "present," "since 1940," etc. EXAMPLES Instead of: Encs. 3 (1) Recently, Dr. A. O. C. Nier isolated U-235 (2) Twenty-six years ago, the U.S. entered World War I (3) Sugar is now rationed in the United States (4) Since 1940, Anthony Eden has been foreign minister.
