See there is two problems,
this book is scanned so sometimes the pages are not placed perfectly on the scanner
the result is, some pages is slightly slide to left or right
that will cause most simple OCR programs to fail!
also in some pages the font is either very pale or very bold
both cases causes problem for the OCR
I am not trying to disappoint you, but I am trying you let you know my experience so that you don't have to pass through the same problems I had
