→Video resources listing every source.
Choose a video to watch, explore its sources, take its quiz and read any published corrections. Everything related to that video, on one page.
iHow this page works. The list is pulled live from the YouTube channel and numbered backwards from the newest video, so new uploads appear on their own. Vertical Shorts are excluded and never take a number. A sources document named after its video's number —
717.pdf for video #717 — attaches itself to that video automatically; if a video says the document is coming soon, it is still being compiled. Videos older than the live feed keeps are in the sources archive above.
