Re a proposed paperback edition of Volume I of Principia Mathematica.

"As I am sure you realise, a great many undergraduates (both in this country and in America) reading logic or a general course in philosophy are often led to refer to the introductory parts of Principia Mathematica. The more detailed and technical discussions which follow are probably for the most part beyond their scope; and we are sure that at the moment most of them simply borrow Volume I from a library and use it from time to time. If the parts most needed by undergraduates were available fairly cheaply in a paperback, it seems pretty certain that a great many of them would buy such an edition for themselves."
