Two abridged indexes of Yudkowsky's sequences are XiXiDu's guide, or Academian's guide targeted at people who already have a science background.

Bolded essays are more important than other posts in the sequence, while italicized essays are relatively unimportant.Small essays are also less important, and are sometimes left out of the post listing altogether. Some essays are indented to indicate that they are tangents or self-contained elaborations upon a previous essay.

Bolded essays are more important than other posts in the sequence, while italicized essays are relatively unimportant. Small essays are also unimportant,less important, and are sometimes left out of the post listing altogether. Some essays are also indented to indicate that they are tangents or self-contained elaborations upon a previous essay.

Of these, "Map and Territory," "Mysterious Answers to Mysterious Questions," "How to Actually Change Your Mind," and "Reductionism" were classified as "core sequences." There was also a distinction between "major" and "minor" sequences, though this was based on the size of the sequence rather than its importance.
