Download the "Overdrive" app from whichever store supports your device (e.g. Google Play, Apple Store). Open the "Overdrive" app and link to your library of choice and then log into that library, assuming you have an account - make sure it remembers this info so you don't have to key in your account info each time. Once in the library, you can search for the item you want (I like advance search to pinpoint what I'm looking for) and check it out. This process can be a little different depending on the device you have (e.g. Google, Apple), but in general you will have the library material downloaded to your "bookshelf" and can view it. I suggest viewing it immediately upon download to ensure it's on your device versus finding out at a slow internet connection airport that it didn't initially download and then have to wait 30 minutes for the download - been there, done that. I hope this helps.
