How CourseLegend works

Field → where a subject or occupation lives.

Resource type → what kind of material you want.

Collection → a curated bundle that connects several useful resources.

Wiki → an explanation when the concept itself is worth maintaining.

Most resources stay as concise external links inside the most useful section. Dedicated CourseLegend pages are reserved for material that benefits from explanation, comparison or deeper context.
