How to Mark a Book as Read in iBooks

Open iTunes. Click the 'File' menu and select 'New Smart Playlist.' Alternatively, press 'Alt,' 'Cmd' and 'N' (at the same time) to open the 'New Smart Playlist' dialog box. This begins the process of creating a new playlist that filters its own contents on your behalf and will only contain unread books. Ensure the 'Match the following rule' box is ticked.
Click the 'Artist' drop-down box and scroll down. Select 'Playlist.' The next two drop-down options turn to 'is' and 'Music,' respectively. Click the 'Music' box and scroll down. Select 'Books.' The first rule in your new 'Smart Playlist' is now set. Click the '+' button. This begins creating the second rule.
Click the 'Artist' drop-down box and scroll down. Select 'Plays' this time. The next two drop-down options turn to 'is' and '0.' Leave these alone, as the rules are now set correctly for the playlist to only include unread books. Click 'Okay.' The playlist name is highlighted in the left sidebar. Enter the name 'Unread books' and press 'Return.'
