The Gmelin Formula Index and its First Supplement covered those volumes of the Eighth Edition of the Gmelin Handbook which had been issued up to the end of 1979. The present Second Supplement updates the Index by inclusion of the volumes which appeared until the end of 1987. With this Second Supplement all compounds described in the Gmelin Handbook of Inorganic Chemistry in the period between 1922 and 1987 can be located. The basic structure of the Formula Index remained the same as in the previous editions. The cumulated contents of the Index and its Supplements are contained in the Gmelin Formula Index (GFI) database which is available to the scientific community via STN. This database will be update regularly to reflect the published Handbook volumes as close as possible. Volume 4 of the 2nd Supplement contains 11.730 entries and covers the empirical formulas beginning with the symbols C7 to C11.4.
