if the goal is just to be able to read the pages and learn songs, rather than print perfect copies, the various programs mentioned can help...I haven't found anything yet I couldn't read ok with CompuPic and Paint Shop Pro and a little magnification...both of these have built in algorithms which do some 'cleaning' and enhancing of fuzzy images...not as good as the serious tricks Ralph is referring to, but adequate...and maybe the site will eventually do some re-scanning along the lines he suggests.
