TOPICAL CLASSIFICATION OF CONTRIBUTIONS. No article is entered under more than one head, although some are more comprehensive than the classification indicates. The titles are often abbreviated; the full title and the reference to place and date of publication of any contribution can be found by means of the serial number of the chronologic list. The classification covers only more important topics. Many con- tributions are not classified, and some (Reviews, Editorial Comments, Contributions to Encyclopedias) are not enumerated in the primary list.
