Subject: Rationalizing Which Chemistry Databases to acquire ?

We haven't gone with CHEMnetBASE, but we do have the online Combined
Chemical Dictionary (which I think is an excellent product, but not marketed
as aggressively as it deserves).

I have done comparison searches and find unique references in the CCD not
found in SFS and Beilstein. From our perspective the annual cost for the CCD
is about same as the amortized cost of the various print dictionaries.

I feel that the CCD is a 'must have' product since it covers organic,
inorganic, and organometallic compounds as well as natural products,
analytical reagents and pharmacological agents.

I find that the CCD is unique because it provides a wider variety of
references, for the compounds it indexes, than Beilstein/Gmelin or SciFinder
Scholar ( e.g. Aldrich spectra catalogs; Fieser & Fieser's Reagents ...;
Ullmann's and Kirk-Othmer; Extra Pharmacopoeia; Bretherick's Handbook of
Reactive Chemical Hazards; RSC's Hazards in the Laboratory; Sax's
Dangerous Properties ...; Browning's Toxicity and Metabolism ...; Organic
Syntheses (which Beilstein hasn't indexed since 1980); Encyclopedia of
Reagents for Organic Synthesis; and references to book chapters).
