Education & Research
Education and Research collects the places people go to learn something, from university portals and course pages to study tools and academic libraries. Universities have a topic of their own, covering admissions pages, course catalogues, and campus information. Language learning, science and mathematics, and history and humanities each hold their own references. Programming and technology learning gathers tutorials, documentation, and practice sites, while research and study tools lists citation helpers, note taking apps, and reference managers. Online courses, exam preparation, and educational and academic books add further topics, with space and astronomy references sitting alongside them. A few entries point at informal book and paper sources rather than official publishers, so check who runs a page before you rely on it, especially for anything you would cite in written work.
