UT Libraries buys ebooks from many providers, including individual publishers as well as aggregators. This is why our ebooks do not have a single, common platform or interface, and the number of simultaneous users varies.
Many publishers, like Cambridge University Press or Elsevier, do not apply digital rights management (DRM) or user restrictions to their titles. We prefer to buy these models of ebooks, when they are available.
When ebooks are purchased through an aggregator or other third party, restrictions may be applied to printing, downloading, and number of simultaneous users. For some titles considered textbooks, the publishers only offer ebooks that allow one user per copy (as if you were checking out a print copy). Other titles may only be offered in limited models, switch providers, or stop being sold as ebooks entirely.
