How many pages can I copy/print?
Ebook Central e-books are DRM protected, the number of pages you can copy/print varies from title to title. Many publishers will allow you to copy 20% and print 40% of the total pages but others permit significantly less.
Your allowance will be clearly displayed once logged into an e-book.

Regardless of your allowance full copyright law applies.
