Why does it not allow the loan to be RENEWED?

You may find that some titles allow you to renew your loan and others do not. Please note that this is not an error.

The reason why some titles do not allow you to renew your loan is because they have been reserved by other users, and I must point out that RESERVATIONS take precedence over RENEWALS.

This priority is to help users access the resource, since if we did not have it, one user could “appropriate” a resource indefinitely, which would not be fair to other users.

I recommend that as soon as the resource is returned to you, you reserve it again quickly so that you can access a copy as soon as possible.
