The Library provides access to ebooks from many different publishers on a variety of platforms. Some of the ebook platforms include DRM (Digital Rights Management) to protect the content of their ebooks from copyright abuse. This means that you will encounter a variety of limitations in how much you can print, download and save from an ebook. 

Access to ebooks on third party platforms is an agreement between the platform and the publisher; the library has no involvement, except for the right to purchase (or lease) the ebook on an ebook platform.
