Forum:Korinn Archipelago - Why no old map?

Hello all! This is my first post to this forum, so please let me know if my format/method is off.

I've been researching the Korinn archipelago for my current Forgotten Realms game and found some information in the original source for this area, the AD&D adventure N4 - Treasure Hunt by Aaron Allston. Specifically, a map that details which island is which, which I've included in this post. This information isn't part of the wiki article on Korinn; Why is this, do you think? Is there some kind of copyright issue or wiki standard that prevents this? It would have been useful for me to have that info straight from the wiki, rather than digging through an old (but cool) module.

I'm not sure about the copyright or fair-use of this image. I think in this context it's being used for a non-commercial activity. The book that it comes from is out of print and is no longer available, except in used form or as a DriveThruRPG pdf. What's the protocol here?
