Now these systems as we find them are as follows: in nearly all States public and private laws are lumped together, although in a few they are indexed separately. Most of the States to-day, including all the "code" States, adopt the topical system of arrangement, as, indeed, must be the case in anything that might, by any possibility, be called a code, and even a general "revision" of the statutes will naturally fall into chapters covering certain subjects. A few States, as I have said, cling to the crude alphabetical system, and quite a number have no discernible system whatever. In some States the annual laws are arranged by number, in some by date of passage, and in some apparently according to the sweet will of the printer. In those States which do not arrange them or entitle them by date of passage we have to depend on the crude and dangerous system of citation by page. Acts of Congress are sometimes cited by date of passage, sometimes more formally by volume and number of the Statutes at Large, and more often than either, probably, by the popular name of the statute, such as the "Sherman Act," the "Hepburn Act," or the "Interstate Commerce Law." It seems to me we should recommend one system. That for the codes or general revisions should certainly be topical. That of the annual laws may either be topical or chronological, but the statutes, in whatever order they are printed, should be _numbered_ and cited by number. No alphabetical arrangement ever should be permitted.
