Hi, I have found some survival books on google free books but, what good will they do if I can't use my computer?

So it occurred to me - what if I converted the PDF file into a new file but it was in micro print. So small that you'd need a laser printer to print it and a Microscope to read it? (maybe bigger that that, but really small unreadable without magnification) That way I can print it store it with out having to carry around a five hundred page book?

Any ideas or software (free?) packages that can do this?
