4. _Registration number._ Prior to January 1, 1900, all works were numbered in sequence as they were registered, and a new series of numbers was established at the beginning of each calendar year. In citing the number for any registration made during this period, the year date must, therefore, be given. To achieve brevity, however, the year date is not repeated in the entry in connection with the registration number, because the number immediately follows the full date in each entry. Beginning with January 1, 1900, the material received in the Copyright Office was divided for purposes of registration into classes designated by letters of the alphabet. Three different series of classes were used in chronological sequence during the next 12 years; in consequence, the registration numbers of motion pictures registered as photographs included in this catalog are preceded by class designations as follows: January 1–December 31, 1900 D January 1, 1901–June 30, 1909 H July 1, 1909–January 23, 1913 J _Sample Entries_: THE AWKWARD MAN; or, OH!
