“In one memorable episode, Warren received a trusting note from a woman in the bookkeeping department via the library’s pneumatic-tube system, which ran between the library and store. “It’s very slow here on this rainy day,” the bookkeeper complained. “Please send me one of those novels you have had to withdraw from circulation as unfit for a lady to read.” Warren fulfilled the request and was surprised the next day to receive the book back, discreetly wrapped, with the message: “Blessings upon you! You’re quite right. This is not fit for anybody to read. Please send another just like it.”
