A system for easily determining viewership of articles or ads in printed
publications and using the determined viewership to determine author
compensation, ad rates, or other historical or demographic related
information is described. The system receives scan information of
portions of a number of paper documents that is generated by scanners
operated by a number of users. The system searches digital content using
the received scan information, and determines a readership value for
components of the paper document based upon the search.
