MIT Press now distributes the second edition of the book Structure and Interpretation of Computer Programs (SICP) in HTML format. Lytha Ayth converted the book to Texinfo format, so that the book can be viewed in Emacs. S/he apparently redrew all the figures using ASCII text characters, which is rather perverse.

I've made very minor modifications to a version of sicp.texi that was circulating informally at MIT, and distribute my modified version (and a compiled sicp.info of it) via this Web page.
