There are no official ebooks of SICP, but there are a few unofficial ebook conversions from the free web version. Here are the two best versions I’ve found:
Ian Eure’s epub version, for iBooks and various other non-Kindle readers. You used to be able to download the epub directly from that repo, but GitHub has discontinued download hosting. This direct download link (thanks, Michael Tsai) should work for awhile.
- There are at least a couple of Kindle versions; of which the better is Tim Camper and Jonathan Patt’s mobipocket version. The mobi file is actually versioned in the repo, so you can download it straight from there.
