If you’re looking for textbooks, lecture notes, or papers in a specific field, sometimes the best move is to find a well-curated list first rather than searching blindly. This post collects exactly those kinds of aggregator pages — meta-resources that point to other resources.
General Physics Aggregators
Gerard 't Hooft — “How to Become a Good Theoretical Physicist”
A Nobel laureate’s personal roadmap through all of theoretical physics, organized by topic with recommended texts and online materials for each stage.
David Tong — Lecture Notes (Cambridge)
Freely available lecture notes covering classical mechanics, electrodynamics, quantum field theory, string theory, and more — widely regarded as among the best available.
The Feynman Lectures on Physics (Online Edition)
The complete three-volume Feynman Lectures, freely accessible and officially hosted by Caltech.
MIT OpenCourseWare — Physics
Full course materials (problem sets, exams, lecture notes, and some recordings) for MIT’s physics curriculum, from introductory mechanics to graduate-level courses.
PhysicsForums — Science and Math Textbooks
A large community-maintained thread collection covering textbook recommendations across all physics subfields, vetted by active researchers and educators.
Open-Access Textbook Repositories
Open Textbook Library — Physics
A curated index of peer-reviewed, freely available physics textbooks with quality ratings from instructors.
arXiv Physics
The primary open-access preprint server for physics research; covers all subfields including mathematical physics, condensed matter, HEP, and quantum physics — also hosts many pedagogical notes.
Project Gutenberg — Science & Physics
Public domain physics texts, useful for historical primary sources (Maxwell, Hertz, Mach, early quantum papers).
University Course Page Aggregators
Perimeter Institute Recorded Seminar Archive (PIRSA)
Thousands of recorded lectures and talks from the Perimeter Institute on topics ranging from quantum gravity and cosmology to quantum information — graduate and research level.
CERN Academic Training Lectures
Recorded lecture series on particle physics, accelerator science, and related topics, delivered by active CERN researchers.
Les Houches Lecture Notes (via arXiv)
Many of the famous Les Houches summer school lecture notes are freely available on arXiv — a reliable source for authoritative introductions to advanced topics.
Field-Specific Meta-Lists
John Baez — “How to Learn Math and Physics”
An opinionated and carefully structured reading list by mathematical physicist John Baez, covering algebra, geometry, classical/quantum/statistical mechanics, and QFT.
r/Physics Wiki — Book Recommendations
Community-curated list organized by subfield and level — useful for a quick second opinion or discovering less-obvious texts.
Stack Exchange Physics — Resource Recommendations
Searchable archive of community-vetted resource recommendations, filterable by topic (e.g., quantum optics, general relativity, condensed matter).
Tools for Managing and Discovering Papers
Semantic Scholar — Physics
AI-assisted academic search engine covering physics literature, with citation graphs and paper recommendations.
Inspire HEP
The canonical literature database for high-energy physics, quantum field theory, and related fields — includes citation tracking and author profiles.
NASA/ADS (Astrophysics Data System)
Comprehensive database for astrophysics and astronomy, with full-text access to many papers.
This list will be updated as new resources are found. Feel free to reply with additions, but please follow the category format: link + one-sentence description.
