Download, full document: Duration for downloaded e-books

An ebrary document downloaded as an e-book in Adobe Digital Editions or on your iOS device is only available to you on a temporary basis.Multi-user document = 14 days

If your ebrary site has multi-user access to an ebrary document, your downloaded e-book of that document will be accessible for 14 days.  Note, all ebrary documents in subscription collections on your site are multi-user.

Single-user-only document = 7 days (if at all)

If your ebrary site has single-user-only access to an ebrary doucment, you might not be able to download it as an e-book (it depends on your administrator's settings).  If you can download it as an e-book, it will be accessible for 7 days.  While you have it downloaded as an e-book, other users on your ebrary site cannot access the document - not even for online viewing - so consider returning it as soon as you're done with it.

After the designated access time (14 or 7 days), the .pdf file will remain on your computer or device, but it will become unreadable (think Mission Impossible's self destruct timer ticking away).  Once it times out, you might want to delete the (unreadable) file to avoid confusion.Returning a downloaded e-bookYou don't need to return an ebrary downloaded e-book.  But since you can only have ten ebrary documents downloaded as e-books at a time, you might want to return an e-book early so you can download others.  And returning a single-user-only downloaded e-book will make it once again available to others on your ebrary site.  Early returns of downloaded e-books are done through Adobe Digital Editions, or an app (such as BlueFire) on your device.  Returns may take up to an hour to be recognized on your ebrary site.For more details on returning a downloaded e-book, see:
