If the jokes about my superpower have any strength, it’s in a comfort with digging around in archives (even digital ones) and finding things that are maybe not hidden, but that are not the first thing to come up in google, or wikipedia.
This list is where a lot of that skill comes from. The knowledge of where to look for items is one that took me time to learn, but this at least gives a single collection of options for those who don’t necessarily know where they will find the specific kind of item that they are looking for.
Please feel free to drop me a note here if you have a source that you think should be listed, or you have found an issue with one of the links above.
New resources do not have to be free, but they need to be a useful source in some way, even if someone can’t pay for access.
