The relevant documentation is
http://www.faqs.org/docs/bashman/bashref_29.html#SEC29

FWIW I prefer the shorter $var (less typing), and only use braces when
absolutely necessary (string manipulation, $var is followed by a
character that is not to be interpreted as part of the variable name).

Cheers,
Michael
