I’m happy to announce that Narumi Katoh has just completed a new Japanese translation of SICP. The amount of work and attention a translation requires is just astonishing, for that I bow in deep gratitude.
From the introduction to Unofficial Texinfo Format:
There are only a few apps that render the epub3 version fairly, but still not correctly. Readium, Azardi Desktop, and iBooks are almost there. While we wait for the other readers to mature, we can read the HTML5 version in a browser (tested in latest Firefox, Chrome, and Safari).
For reading on e-book readers and small tablets, a pocket version of Structure and Interpretation of Computer Programs is now completed: sicp-pocket.pdf, or an alternative with tiny margins: sicp-marginless.pdf. It has 1133 pages, 93 diagrams, 356 exercises, and 29192 parentheses! Source repository: sicp-pocket.
This is an update to fix a few typos found in the first three chapters. Other than that, there are cosmetic changes to the diagrams and page layout. Text leading has been reduced and page margins adjusted. Denser flow of text has brought the page count down from 939 to 795. Have fun reading, watching the videos, and playing with the REPL!
EDIT 2012/11/25: newer version of the PDF.
The PDF version of the classic MIT 6.001 computer science textbook Structure and Interpretation of Computer Programs (SICP), 2nd ed. by Abelson, Sussman & Sussman just got better.
The typography has been modernized for better on-screen legibility and comfort. All the mathematics is set in proper TEX, and figures redrawn in vector graphics.
