I just remembered there is another item that we can all post locations for as well. Lore Books help level up the Mage Guild. I'll start another thread on the guilds.
Anyhow, this will be similar to the Skyshards. When you find one of these, open your map, mark the spot on your map, take a screenshot, and attach you screenshot here (after NDA has been lifted).
Keep in mind, there are books and lore books in the game. Reading a book does give you some experience and a bunch could help level you up in various skills. Reading a Lore Book is similar, but also gives you XP towards the Mage Guild. I think these give even more xp to various skills as well. I'm not 100% sure how books work since I know I was going up in levels for skill trees I wasn't even using.
