Secondary sources of chemical information. Abstracting journals

A,3. SECONDARY SOURCES OF CHEMICAL INFORMATION. ABSTRACTING JOURNALS... 

Accuracy in an abstract journal is naturally of interest to users. Too many mistakes get into Chemical Abstracts, Nevertheless a good deal of care is exercised to keep abstracts accurate (much checking is done). Because an abstract journal is secondary information, not source material. Chemical Abstracts does not publish an erratum section, but the more serious mistakes and omissions discovered are corrected by the use of supplementary abstracts or by suitably worded index entries.
