Audiences and critics acknowledge that a play or concerto gains force in great rendition. A good play may overcome bad staging. A great concerto may survive a poor soloist. But it is naturally assumed that a more accomplished performance intensifies the impact of the work. The play's text or concerto's score does not change, but the right actors and musicians help realize its full potential. Among contemporary literary critics, however, one never encounters this notion in regard to books and printing. To recognize the sensual contributions of the physical elements of a book is somehow assumed to demean the spiritual purity of the text. To notice the book itself smacks of philistinism, and to make distinctions based on paper, binding, and typography brings accusations of elitism or decadence.
