You have to select the Sync option and then check the categories, ie, books, pictures, music, etc. that you want to sync. If you haven't actively checked anything, then the sync option is not turned on, thank goodness! When I checked it to sync my books, at the time I had created over 100 bookmarks on my reader, it tripled my bookmarks and made it nearly impossible to open a book. I had to delete everything (over 250 books) and start over. After this happened 2 times (okay, I'm a little hard-headed

), I finally wised up, turned of the sync, and started creating the bookmarks using the library software on my laptopn and then downloaded the books to my reader -> One-Way!
