Oliver Wendell Holmes, Jr., Smith v. Hitchcock — Opinion of the Court
“ As books are not turned into periodicals by number and sequence, the magazines are not brought into the third class by having a considerable number of pages stitched together. Without attempting a definition, we may say that generally a printed publication is a book when its contents are complete in themselves, deal with a single subject, betray no need of continuation, and, perhaps, have an appreciable size. ”
