I'd agree with knowledge organization. It's either you have to root through academic texts or try and navigate the spammy internet with no really happy medium. It's almost like there's a complete lack of quality middle ground information. It's either total SEO garbage or very low quality entry level information or incredibly specific/dense academic content and the middle ground is missing.

Back when I was in grad school, PhD theses were indispensable for actually learning my way around a topic.

The academic literature itself (even review papers) was way too terse and (I believe, semi-intentionally) obfuscatory.

I would assume that it hasn't changed much since you were in grad school.
