由 Library Journal 所執行 2011年美國圖書館電子書普及程度與使用調查( 2011 Ebook Penetration & Use in U.S. Libraries Survey) 結果顯示，電子書的需求與採購在公共圖書館方面有極大的成長，電子書成長比例達184%。學術圖書館的電子書成長比例雖只有93%，但數量卻也相當驚人。
下面是取自 The Digital Shift 報導中幾項數據及圖片：
- 66% of public libraries reported a steep increase in ebook requests, and 82% now offer them. They expect ebook circulation to double this year. That doubling is made possible by more robust collections: public libraries increased their offerings by 185%.
- Academic libraries are almost all on board, with 95% offering ebooks; their ebook collections increased by 93%. They expect more growth in circ, and to see 19.1% of their budgets go to ebooks in five years.
- 15% of public libraries and 12% of academics currently circulate preloaded devices, and 26% and 22%, respectively, expect to in the future.
- 62% of public libraries and 58% of academics now buy ebooks via a consortium, and 37% and 76% also buy ebooks independently.
