In considering the subject-heading for this book, we have the choice of synonymous terms, viz., Economics and Political Economy. The first is the more modern term which is gradually supplanting the other in use, and for that reason it is the better to adopt. Having made the choice definitely, we at once proceed to write a cross-reference, which will prevent the placing of any other book upon the same subject under the discarded heading whatever be the terms on the title-page. The reader will be thus guided to the heading which has been chosen for the subject. It is a fundamental principle of the dictionary catalogue, which cannot be too often impressed upon the cataloguer, that a book is entered under its specific subject quite irrespective of the terms used upon the title-page, and that two books upon the same subject ought not to be in two places. Accordingly the reference to this end will be
Political Economy. See Economics.
