"This book is to be published under the aegis of a commercial publisher, which means that royalties are involved. But since scientific books generally have a limited audience, a royalty income is minuscule, but young and naive authors have visions of a Mercedes-Benz in the royalty picture. Factually, my last royalty check on a book produced a few years back was forty-six cents! I did not cash it and the publisher wrote me, "Why don't you cash your royalty check." I said it would cost them a dollar to cash that check for forty-six cents but they insisted I do so to meet legal requirements and also to facilitate their bookkeeping!"
