Becher tries to convince BR in publishing the paperback edition of Volume I of Principia Mathematica.

"I really do believe that the paperback would have no serious effects on the sales of the complete three volumes.... When we were planning to issue a paperback of Moore's Principia Ethica, Mrs. Moore was most anxious lest this should have an adverse effect on her income from the book (and of course here, the text of the paperback was identical with the text of the cloth edition ...). As it has turned out, her annual royalty statements are now more than double the previous average."
