A sequence is a series of multiple posts on Less Wrong on the same topic, to coherently and fully explore a particular thesis. See the Library page for a list of LessWrong sequences in their modern form.

The original sequences were written by Eliezer Yudkowsky with the goal of creating a book on rationality. MIRI has since collated and edited the sequences into Rationality: From AI to Zombies. If you are new to Less Wrong, this book is the best place to start.

Rationality: From AI to Zombies is an ebook collecting six books worth of essays on the science and philosophy of human rationality. It’s one of the best places to start for people who want to better understand topics that crop up on Less Wrong, such as cognitive bias, the map-territory distinction, meta-ethics, and existential risk.

The ebook can be downloaded on a “pay-what-you-want” basis from Its six books in turn break down into twenty-six sections:

Benito’s Guide aims to systematically fill the reader in on the most important ideas discussed on LessWrong (not just in the sequences). It also begins with a series of videos, which are a friendly introduction, and useful if you enjoy talks and interviews.

Thinking and Deciding by Jonathan Baron and Good and Real by Gary Drescher have been mentioned as books that overlap significantly with the sequences. More about how the sequences fit in with work done by others.
