I can't find any detailed information on this outside of this post. What kind of Library Of Congress resources are there? Is there anywhere to discuss things with other people?

GPT means there's lots of opportunity to do more qualitative stuff, similar in spirit to Oregon Trail, than there used to be. There's lots of issues with anything that uses GPT interactively (fun as that can be), but pre-calculating a ton of narrative material (including structured material) opens up a lot of possibilities.
