Under US copyright law:

Copyright protects the particular way an author has expressed  
himself; it does not extend to any ideas, systems, or factual  
information conveyed in the work.

SO, if you rewrite it without quoting it is fine to do so.

One of the rights accorded to the owner of copyright is the right to  
reproduce or to authorize others to reproduce the work in copies or  
phonorecords. This right is subject to certain limitations found in  
sections 107 through 118 of the Copyright Act (title 17, U. S. Code).  
One of the more important limitations is the doctrine of �fair use.�

Section 107 contains a list of the various purposes for which the  
reproduction of a particular work may be considered �fair,� such as  
criticism, comment, news reporting, teaching, scholarship, and  
research. Section 107 also sets out four factors to be considered in  
determining whether or not a particular use is fair:

the purpose and character of the use, including whether such use is  
of commercial nature or is for nonprofit educational purposes;
the nature of the copyrighted work;
amount and substantiality of the portion used in relation to the  
copyrighted work as a whole; and
the effect of the use upon the potential market for or value of the  
copyrighted work.
