   '(something) is just an abbreviation for
   (quote something).

This is not correct.

 '(something) ≡ (quote (something))
 which evals to a list of one element, the symbol ‘something’
 i.e., => (something)

but

 (quote something) ≡ 'something
 which evals to the symbol ‘something’
 i.e., => something

Also, i think it's better to say "evals to" rather than "returns".
The latter strikes me as indicative of a function-call context.
OTOH, ‘eval’ is a function, so i suppose YMMV...  :-D
