Collective Indexes of Chemical Abstracts

Year Spans

Please note: SFS has renumbered all abstracts in 1st-5th to unique numbers.  CA references in older volumes, and old sources such as Beilstein or early volumes of Organic Syntheses may not connect to the correct item when searched in SFS. 

 (1st)    1907-1916

(2nd)    1917-1926

(3rd)    1927-1936  1930--unique CA abstract number now available (column is numbered + fraction of page)

(4th)     1937-1946

(5th)    1947-1956

The first 5 cumulative indexes were not numbered.  No notation on naming in these early volumes is available in the Registry file.
