It looks like, though, that the sicp.mobi file is from the original repo (revision date of Jan 10) and the fork that this post points to includes a series of improvements to the text (revision date of Sept 18) that the .mobi hasn't been updated to take advantage of. Thus, it looks like the .mobi needs to be recompiled to include the improvements that @jonathanpatt has committed. There is also a pull request on the original repo that should likely be included in any revision, too: https://github.com/twcamper/sicp-kindle/pull/5 https://github.com/twcamper/sicp-kindle/pull/5
