There could be a couple of reasons why you might see this message.
SomeeBooksuppliers sell eBooks with a credit licence, ratherthan a concurrent user licence. We buy aneBook, and pay for a set number of uses of that eBook per year. If we use up more than the agreed number of uses in one year, we lose access unless we buy another copy of that eBook. We buy additional copies of popular eBooks. However, some publishers only sell eBooks with a 100 uses at one time and if they are in very high demand these credits are quickly used and there might be a delay while we buy additional copies of the eBook if the credits run out overnight or at the weekend.
eBooks on the VLeBook website also use a credit system to regulate how many eBooks a user can access per day in order to protect the system against misuse. If you get an error message telling you that you have used too many credits please email firstname.lastname@example.org so we can investigate further.
