Someone has taken the time to scan in a whole collection of their Classics Illustrated books.  If you like these, check out this link:

I Have argued vehemently against letting children have those books, but it's kinda cool to have them available online.

I'm not a fan of them in place of reading the real thing, but I know some folks like them.  I do think they can be a nice introduction for kids who are way too young to read the real thing--so long as the subject matter is appropriate.
