body: If I write a book and I cite the works of other authors, what are the legal requirements for the citation? For example, I want to take about 1 or 2 sentences verbatim from the book titled 'The 7 Habits of Highly Effective People'
  
  
  I assume that I have to include the name of the author and the name of the work, which I am citing. What else must be included?
