It sometimes happens that there are people who do not know that authors and editors and the Titles of Books and Series are protected by copyright laws, and also by what is more binding, - Professional Courtesy. Since publishing "Poems Every Child Should Know," a very curious case of legal infringement and professional infringement has come up. There are some things that an editor can't do and be a gentleman. And another thing that an editor of books can't do is "to hustle" and "rush things into print." No valuable editor or author will do any work except from an inner leading, and out of a full heart and a full knowledge. He will do nothing on time, nor under superintendence; nor will he do for a new firm what he has already done for an old firm or anything that competes with any one.<br><br>Special permission has been obtained under the laws of courtesy, as well as the copyright laws, for each copyrighted selection in this volume, and the right to publish has been purchased, except in those cases where the author or the publisher has, for reasons of friendship, given the permission. In addition to business arrangements, we wish to extend our thanks and acknowledgments to those firms which have so kindly allowed us to use their material.
