We will always try to buy the version of an e-book that gives the most access to the largest number of readers. Sometimes, however, we have had to buy e-books that have limits on the number of readers that can access them at the same time. If you try to access a limited-user e-book at the same time as other readers, you may get a message that says that the book is unavailable because the maximum number of users has been reached. You may also be offered a place on a waiting list to access the book. If you find you are frequently being refused access, or "turned away" from an e-book, please contact our Content and Digital Systems team at libline@essex.ac.uk. The team will check to see if an alternative provider is available.
