The etc. part of the Library
Here's the media I've watched/read/listened to that don't necessarily fit into the other categories.
Gemini Home Entertainment: What I consider one of the best analog horror series, GHE consists of a collection of home video tapes that hide things that are quite... eldritch. Definitely recommend, but watch out for body horror.
The Magnus Archives: Horror podcast that starts with an archivist recording statements (which are essentially short horror stories) and evolves to something more complex. The statements are definitely the best part of the podcast, with the 'meta plot' falling a little flat for me. S5 and its ending also ended up rather mid. Mostly read the transcripts, didn't feel like listening to the audio itself, but you probably should actually listen to it ^^
Archive of the Odd volumes 1-5: Organization mainly focused on publishing zines and other writing that are unconventionally formatted: whether it's in the style of letters, forums, or investigation reports, as long as it's atypical, it can be published in the zine. Formats usually fuck immensely, but the story itself being good depends on the author. The strongest set of stories can be found in volume 2, by the way. Do note you have to pay for either physical or digital, with the latter being much cheaper (around 3 USD).
Book of Mario: Thousands of Doors + 64: ROMhacks where Paper Mario TTYD and 64 respectively get Google-Translated a bunch of times. The result is a chaotic masterpiece. Do note this also ends up with both works acquiring political themes. Highly recommend the creator's- Fatguy703- videos playing both hacks, either through the highlights (what I did!) or the full stream. He and his group of friends can be obnoxious at times, but they do also add flavor to the hack as well.
