title_body: I have a printed version of a book does it allow me to possess an electronic copy? I have a printed version (i.e. a hardback or paperback) of a book and I wonder whether this allows me to possess an electronic version of it (e.g. .pdf file).
  
  
  
  Edit: Isn't it allowed by the clause 107. Limitations on exclusive rights: Fair use., which says
  
  
    Notwithstanding the provisions of sections 106 and 106A, the fair use
    of a copyrighted work, including such use by reproduction in copies or
    phonorecords or by any other means specified by that section, for
    purposes such as criticism, comment, news reporting, teaching
    (including multiple copies for classroom use), scholarship, or
    research, is not an infringement of copyright. In determining whether
    the use made of a work in any particular case is a fair use the
    factors to be considered shall include— 
    
    (1) the purpose and character of the use, including whether such use
    is of a commercial nature or is for nonprofit educational purposes;
    
    (2) the nature of the copyrighted work;
    
    (3) the amount and substantiality of the portion used in relation to
    the copyrighted work as a whole; and
    
    (4) the effect of the use upon the potential market for or value of
    the copyrighted work.
    
    The fact that a work is unpublished shall not itself bar a finding of
    fair use if such finding is made upon consideration of all the above
    factors.

upvoted_answer: Just like buying a hardcover version doesn't let you also take a paperback from the store, no, having a print version does not entitle you to a complimentary ebook version, though some publishers will offer that when you buy from their websites.
