Older books will have been digitized via OCR. (Even books that are new enough that one would have assumed that the author used a word processor.) Unless edited, they will contain many more errors than the paper version. Many publishers have been guilty of releasing these without proper editing. Tossing a bunch of additional errors into the mix drops the value significantly.
