I found a great online resource in Ukraine: https://ouci.dntb.gov.ua/en/ There are lots of places where you can find where recent papers have been cited, but they're not much use before about 1980. This one told me about citations of the early 20th century papers on set theory that are part of my current historical study of the order-theoretic fixed point theorem. Слава Україні!
