Waow, quite a collection you got here. I don’t really have a website where i maintain such list, so i will say some from my selection:
nadeko.net This person hosts a lot of various services and knows his stuff while keeping it otaku enough.
Frutiger aero archive I wouldn’t say i’m too much of a nostalgic person, but the owner is incredibly nice and the archive quality and dedication is golden.
tane.us (does it counts?) the website speaks for itself.
tengu.space this person has good tastes and a nice website selection.
