9. Implications of this Shift
• Larger collections
• Less permanence
– We need to develop solutions
• Portico, LOCKSS, what else?
• Unintended consequences?
– Harder for publishers?
– Fewer books published?

25. How Closely Are P/E Usage
Linked?

26. Increased Checkouts, 2008-2012
• For titles available at the start of the project
(Dec 2008), how many more checkouts were
there by Dec 2012?
• Was that increase linked in any way to eusage?
• Was it linked in any way to type of e-usage?

27. Increased Checkouts 2008-2012
• 686 titles with increased checkouts
– Measuring titles available prior to Dec 2008
• 408 available in both formats
• 235 also had e-use
– 15.5 user sessions per title
– 81.2 pages viewed per title

28. Observations
• Use of E may lead to use of P
• Use of P doesn’t seem to lead to use of E
• If both formats are used,
– they are both used at a higher rate than average
– They have greater meaningful use as e-books
• Pages viewed
• User sessions

29. Thoughts
• If dual format usage is higher by all
measures, does this mean that people’s
preference is for good content, not format?
BUT
• When both formats are available, print is
more likely to be used (53.8% vs 39.2%).
– Does e-discovery drive p-use?
