A BIBLIOGRAPHY OF THE BULLETIN (. . .) OF THE ACADEMY OF SCIENCES OF THE U.S.S.R.

This most complicated of all periodicals was first published as the Bulletin scientifique [A], ten volumes of which were issued from 1836 to 1842. It was then divided into two parts, the Bulletin de la classe historico‐philologique [B] and the Bulletin de la classe physico‐mathématique [C]; both were published from 1842 to 1859, the former in sixteen volumes, the latter in seventeen. The two sections were then re‐united as the Bulletin [D], thirty‐six volumes of which appeared in 1859–94(?). The journal was then given a Russian title, . . . [E] and called the fifth series; twenty‐five volumes appeared in this form in 1894 to 1906. A sixth series [F], under the same title with several secondary variations, in twenty‐one volumes, was issued in 1907 to 1927. The seventh series was again divided into two parts, humanistic [G] and scientific [H]; the former appeared from 1928 to 1930, in three unnumbered volumes, the latter from 1928 to 1935 in eight unnumbered volumes. The humanistic series then ceased, but the scientific one was subdivided into four parts, devoted to biology [I], geology [J], chemistry [K], and physics [L]; these began publication in 1936 and are in progress, except the part devoted to chemistry, which was merged in another journal published by the Academy. In the following year (1937) other sub‐sections were added, devoted to mathematics [M] and to geography and geophysics [N]. In the meanwhile a new main class devoted to social sciences [O] had been added in 1931 to the humanistic and the scientific. Later further new classes were created, a chemical one [P] in 1940, a literary and linguistic one [Q] in 1940, and a technological one [R] in 1937; these are all in progress.
