As mentioned yesterday... I picked up an essay by Craig Mod on cover art for eBooks. I did a bit of digging... as I normally do... and found out Mod is the founder of a really cool publishing enterprise called Pre/Post Books.
Whilst the physical artefacts his publishing house creates are truly spectacular... what really captured my attention is his series of Post-Artefact eBooks.
Utilising the Amazon "singles" format... Mod has created three more eBooks that look at books in the digital era. They aren't huge books... around the 35 page mark... but if there writing is anything like Hack the Cover then they'll make excellent and inspirational reading material.
