“CHICAGO — Locked in a climate-controlled vault at the Newberry Library here, a volume titled “The Pen and the Book” can be studied only under the watch of security cameras. The book, about making a profit in publishing, scarcely qualifies as a literary masterpiece. It is highly valuable, instead, because a reader has scribbled in the margins of its pages. The scribbler was Mark Twain, who had penciled, among other observations, a one-way argument with the author, Walter Besant, that “nothing could be stupider” than using advertising to sell books as if they were “essential goods” like “salt” or “tobacco.” On another page, Twain made some snide remarks about the big sums being paid to another author of his era, Mary Baker Eddy, the founder of Christian Science.” #marginalia - × × ×

“Like many readers, Twain was engaging in marginalia, writing comments alongside passages and sometimes giving an author a piece of his mind. It is a rich literary pastime, sometimes regarded as a tool of literary archaeology, but it has an uncertain fate in a digitalized world. “People will always find a way to annotate electronically,” said G. Thomas Tanselle, a former vice president of the John Simon Guggenheim Memorial Foundation and an adjunct professor of English at Columbia University. “But there is the question of how it is going to be preserved. And that is a problem now facing collections libraries.” #прокниги #processed_book - × × ×
