“Not intensely bloody decapitation, but the sort of violence you'd see in a fifteener.”

“When here and there throughout those volumes you meet with titles of books now either unknown entirely or of the greatest rarity; when you find the Colophon from the end or the "insignum typographi" from the first leaf of a rare "fifteener" pasted down with dozens of others varying in value, you cannot bless the memory of the antiquarian shoemaker, John Bagford.”
