I am one of those who have heard about ISBNs but really don't know anything about it.  If you are clueless about ISBNs then this is the best book to read.  The author explained fully well what ISBNs is all about so that you will not remain in the dark.  This is especially helpful for authors and publishers so that they will know where to get ISBNs at reasonable prices.
