How Closely Are P/E Usage Linked?电子书与纸本书的使用是如何紧密关联的?

Increased Checkouts, 2008-20122008-2012 年借阅量增加
• 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 e-usage?• 增加的借阅量与电子书使用是否相关?• Was it linked in any way to type of e-usage?• 增加的借阅量与电子书类型是否相关?

Observations
• Use of E may lead to use of P• 电子书访问量会增加纸本书使用• Use of P doesn’t seem to lead to use of E• 纸本书使用不会增加电子书访问• If both formats are used,• 纸本和电子都被使用的图书中
– they are both used at a higher rate than average– 纸本和电子使用率都会增加– They have greater meaningful use as e-books– 电子书使用更有意义
• Pages viewed• User sessions
![Page 29: eBooks’ Impact on Print: A Library Perspective图书馆视角下电子书对纸本图书的影响8 michael levine clark e-books' impact on print(eng-cn)](https://reader031.fdocuments.net/reader031/viewer/2022031612/5558af1bd8b42a7e298b473a/html5/thumbnails/29.jpg)
Thoughts
• If dual format usage is higher by all measures, does this mean that people’s preference is for good content, not format?
• 如果双重形式的图书使用率更高,是否意味着人们更倾向于内容,而非形式?
BUT• When both formats are available, print is more likely to be
used (53.8% vs 39.2%).• 如果双重形式并存,纸本书使用率更高(纸本书 53.8% ,电子书
39.2% )– Does e-discovery drive p-use?– 电子书使用是否会增加纸本书使用?
