Transferring .epub files to your iPad

Transferring .epub files purchased outside of iTunes seems to be very easy. Download the .epub file to your computer. Open up iTunes and select File -> Add to Library... menu item. From the file chooser, select the .epub file that you want to transfer to your iPad. Click Choose and the eBook file will be added to your Book Library in iTunes 9.1. Sync as usual and the book will show up in iBooks.
