If a Kindle book is checked out again or that book is purchased from Amazon, all of a customer’s annotations and bookmarks will be preserved.
“We’re doing a little something extra here,” Marine continued. “Normally, making margin notes in library books is a big no-no. But we’re extending our Whispersync technology so that you can highlight and add margin notes to Kindle books you check out from your local library. Your notes will not show up when the next patron checks out the book. But if you check out the book again, or subsequently buy it, your notes will be there just as you left them, perfectly Whispersynced.”
Is this standard for Overdrive? Thats who Amazon is working with...
