I don't understand why you need to wait for ebooks if they are sent electronically?
The Omaha Public Library system pays a license fee for each title we provide for check out. If it is a very popular title, the library will purchase mulitple "copies". However, it is possible that all available copies will be checked out. You then have the option to place your name on the request list for that item. You will receive an email when the item becomes available for you to check out. Please let us know if you have any questions.
