Abstract
The first thing you might observe when
you go to purchase a book is the category
into which it falls - expensive, or not expensive.
The following factors have a bearing
on a book's worth: 1) supply and
demand; 2) qualification and authority of
the writer; 3) quality of the physical volume,
i.e., binding, paper, color plates,
etc.; 4) practicality of the contents- can
you actually use the information in the
book?
