If all copies under a title are checked out, you will see a Place Hold on E-book/E-audiobook link on the result list or record details screen.
You will be prompted to log in with your library account, if you have not already done so.
After logging in, you will be directed to the following screen.
Click Place Hold and enter your email address. This address will be kept in the hold record at OverDrive separate from your library account. If you wish to use another email account to receive notification after holds have been placed, you need to update it in every pending hold. Click Place Hold again. Once the hold is placed you will receive a confirmation message and the E-items on hold screen will be displayed.
