The paper attempts to put together the spectroscopic definitions used in the literature for different groups of peculiar objects linked with abundance anomalies.
The groups discussed are:

CNO stars
He-strong stars
He-weak stars
B-type subdwarfs
Ap stars
Am stars
λ Boo stars
δ Del stars
Fm stars
A-F-G stars with weak metal lines
Stars with CN anomalies
Stars with CH anomalies
Ba stars
In each case the useful range in dispersion is quoted and bibliographic references are provided.
