As the publishers desire to issue a second edition of "The Business Library" the following additions and revisions have been made. Articles of value on the subject of business libraries which have been published since the first edition was written have been added to "References for Additional Reading"; minor additions have been made to the text, and the prices and editions of all reference books mentioned have been brought up to date, and some additional titles have been added. Three drawings of floor plans which have been used for business libraries have been added to Chapter Seven as of possible value to business firms making small library layouts. L. B. K.
