If I'm not mistaken, CMS would dictate that an en-dash be used between
"ROM" and "based". This is their style for creating a hyphenated term in
which one of the components is already a hyphenated term. Thus:
CD-ROM--based reference books (where "--" represents an en dash)
From CMS 13:
5.94 The en dash is also used in place of a hyphen in a compound
adjective one element of which consists of two words or of a
New York--London flight
post--Civil War period
_but_: non-English-speaking countries
