A Hint for Publishers

Many, like myself, have no doubt experienced the inconvenience of possessing early impressions of books, of which later editions exist with numerous emendations and errata. Would it not be practicable for publishers to issue these emendations and errata in a separate form and at a fair price, for the benefit of the purchasers of the preceding editions? Were this plan generally adopted, the value of most books would be materially enhanced, and people would not object, as they now do, to order new publications.
