The library provides access to two different models of e-book through ebrary.com. The majority of the ebooks we get through ebrary are part of a 70,000 volume subscription. These books allow multiple people to use them at one time, but they may be withdrawn from the collection at the request of their publishers. The library also buys ebook versions of certain texts; most of these are only accessible to one user at a time.
Browsing a book on Ebrary
When you click on the Electronic Book link in for an item in the library catalog, you may be brought to a screen that looks like this: 
In the right side of the window, you will see the Table of Contents.
Clicking on a chapter title in the Table of Contents will cause the first page of that chapter to be displayed in the left side of the window. 
Clicking on the Left and Right arrows at the top left will let you page through the text.
Putting a specific page number in the Page box will let you skip to that page.
