Curated free websites, official portals, open-access journals, and non-API RSS feeds for 100 subjects across engineering, technology, business, health, social sciences, and arts. Real URLs only — every link verified to point to an authoritative organisation.
This directory is the companion to School Is Cool — every subject hub now has a verified resource shelf behind it. Sources are weighted toward primary authority: government portals, professional bodies (IEEE, ACM, AIChE, AMA, APA), open-access journals (arXiv, PubMed Central, PLOS, BMC), and long-running non-commercial communities (Stack Exchange, OWASP, OEIS, IMSLP). RSS feeds listed are non-API — drop them straight into Feedly, Inoreader, or your reader of choice; no developer key required.
What's not here: aggregator blogs, paywalled trade press without a free tier, content farms. If a source isn't run by the organisation it represents (or by a recognised peer-review body), it didn't make the cut.
Resources for each subject also appear on the corresponding hubs and registries:
