All books have a free browse period (10 minutes for owned books, 5 minutes for non-owned books). When a book is browsed, it is not counted as a loan. When a book is read after the browse period, a short term loan is triggered, which provides access to a single user for a specified period of time (1 day).
There are multiple lending models on Ebook Central, depending on the title's license (set by the publisher):

Unlimited Users (UU)
Unlimited simultaneous users per title.
Three Users (3U)
