<p>interesteddad, great question. According to Harvard, the University Library system offers over 6,820 electronic resources that includes article databases, indexes, encyclopedias, e-book and e-journal collections - that include a mind-boggling number of articles etc. many of which are used for coursepacks. E- Resources are free but tuition only covers the copyright permission of on-line material and not materials printed and packaged in coursepack form. Which of course makes the coursepack even more expensive because students wind up paying copyright permissions twice.</p>
