MANUSCRIPT HUNTING is a variety of book-hunting, but it stands to the hunting of printed books much as chamois hunting does to squirrel hunting, for, while printed books may sometimes be scarce and elusive, manuscripts are always so. Many copies of rare printed books are unique from condition, size, binding, association or, in the case of many incunabula, some slight variation text, but all copies of all manuscripts are unique as to text and nearly all as to handwriting.
