Or, of course, you could use the "standard" procedure for this sort  
of situation: in your main file - say, Book.tex, as above -
have \include{...} for each chapter, and put in the preamble the  
command \includeonly, e.g.,


and change this as you need; this way, you get some very imporant (to  
my mind) benefits: the page numbers are respected, as are any cross- 
references, etc, since, while not typesetting chapter 1 on this run,  
LaTeX does keep and use its aux file, so it knows on which page  
chapter 2 should start, and a reference to Theorem 1.2.5 will still  
be adequately dealt with, as will be citations and things like that.

When you want to work on a different chapter, or typeset the whole  
book, just change the \includeonly line, comment it out or remove
