Hi David,

I've added the roman numerals to your regex, now it will match either 
just the year (2000) or the year + the roman numeral (2000/I) up to VIII 
(I know you said it goes up to III, but you never know)

preg_match('/\((19|20)[0-9][0-9](\/(I{1,3}|IV|VI{0,3}))?\)/',$line,$found);

I haven't fully tested it though (did run it on (2000), 
(2000/I)-(2000/VIII) but that was it).

Also this is still case sensitive, don't know if that matters...
