If you're looking for major/important sources to read on a topic, not just a quick way to halfway-fake a works-cited section, I've found it valuable to locate some representative, recent academic book in the field and read the author's introduction and other pre-chapter-1 material. These will often include a lot of name-dropping of what are considered major works in the field. There may also be a list of abbreviations the book will use, and those often include several major works in the field that'll come up often in the body text.
That's your list of books and papers to find and read. Repeat that technique with each of those books and papers, too, if you want to keep going deeper.
Often you can get enough off an Amazon or Google preview of a book for this to work. Plus, libraries exist, and you pull that kind of information out of several books (which can be handy—anything that appears more than once deserves special attention) in less than an hour, without checking anything out. And there's always Library Genesis, which may not have every book but probably has at least one in your interest area that can be mined in this way.
Wikipedia's sort of useful for this, at least for tracking down a first work to attack with this approach, but the problem is that many articles don't cite highly-regarded or authoritative or landmark works on the topic, so much as whatever the author(s) happened to have handy or what was easiest to find online (a whole hell of a lot of great information is still not available on the Web, even in 2022, including material in very recent books, not just pre-Web ones, or is available on the Web but only in poorly- or not-indexed-by-web-search-engines under-copyright ebooks).
