There was a lot of great EA-related content and research in 2023; I’ve highlighted content that seems particularly notable. Please add content you think should be in a list like this! I'm also sharing excerpts from every month’s edition of the EA Newsletter, in case it’s helpful for some people who might want to look through a low-resolution timeline of 2023.

A companion post lists some reviews 2023 news on AI safety, animal welfare, global health and more. (That post summarizes news, the one you're reading features content.)
