A book has the advantage that you can easily skip thru the critter, flipping back and forth at will, and, most importantly, is easily portable to be used on on the porcelain throne or whilst away from a computer, say, whilst watching TV.

Also, with a book one is less prone to tunnel vision. With a PDF file, one often just finds the point(s) of interest and ignores the rest, thus losing the big picture. A book, in effect, makes it more difficult to lose the big picture.

Bye thee waye, my religion precludes writing in a book and that is one tenet of my religion I would not violate.
