Since there is no in-game Archive or Diary where to check and read the Scannables that we can find around in the game, I thought it could be useful to post the page of Destinypedia where you can find all of them transcribed.
You can find the Scans organized with a very intuitive system that is also explained just before the list.

Kinda a noob question, but I have to ask. As of yet is there another reason for the Ghost Scans other than lore or is this just another situation of the watermark Bungie Background Lore Drop like the terminals in HALO? Just curious. Interesting stuff though. (WHAT IS DOWN IN THE WATER ON TITAN?!?)
