When the subarrangement of the catalogue is by dates (as in that of the Amer. Philos. Society), it may be well to place the date uniformly at the end of the line in this order: O. Wash., 1864. Otherwise the best order is to put the place and date immediately after the title, because like it they are taken from the title-page. The form, which is not copied but is the cataloguer’s own assertion, then comes last. The dates can be made prominent in a chronological arrangement by printing them in heavy type, as in Prof. Abbot’s “Literature of the doctrine of a future life.” In Very Short the German style of printing dates should be adopted, 742 (i. e., 1742), 875 (i. e., 1875). {76}
192. When different volumes of a work were published at different times, give the extreme dates.
Ex. Paris, 1840–42. O. Sometimes Vol. 1 is of the 2d ed. and its date is later than that of Vol. 2. This is in Medium: (Vol. 1, 2d ed.) 1874, 69–73. 5 v. O; in Short merely 1869–74.
