I've converted Tom Judson's open-source Abstract Algebra textbook
(http://abstract.pugetsound.edu) from Latex to a series of Sage
worksheets (one per chapter) with almost no compromises (ie the same
source also builds a faithful PDF). Cross-worksheet links are not
supported yet in the notebook, and I've not yet started adding Sage
code to the book, but adding compute cells is possible and feasible
right now. Available as the first example on the wiki page:

Rob,
This is excellent. It would be useful if these kinds of textbooks were
available
in versions for every CAS. I'll look at what it might take to generate
an Axiom
version. Like the CATS test suites, this could give everyone a common
touchstone
for discussion and debate as well as a common reference for teaching.
The worksheets are packaged into a single zip file, which the notebook
will upload and unpack (mostly even in the right order). There is a
live compute cell at the bottom of each chapter for experiments or
annotation via Tiny MCE. The graphics all begin life as tikz diagrams,
so even these have editable source code.
Tom has done a lot of work to modernize the source, since this book
was originally written in the late 1980's. He had to also update the
Historical Note about Fermat's Last Theorem. ;-) I'll be working over
the next several months to add in material about using Sage to study
groups, rings, fields, etc. Any extra non-obvious ideas about how to
leverage Sage in the study of these topics would be appreciated.
Reports of any typos or technical problems with the current
state-of-the-art would also be appreciated.
I have a few other books in various states of conversion, some have
Sage code already. I'm also going to use Tom's book to further
stress-test MathJax, which has already resulted in two bug-fixes for
the MathJax jsMath-compatibility extension. I've had help from
several people on this, notably Tom Judson, Robert Marik, Dan Drake,
Minh van Nyugen and Davide Cervone.
I'll contribute any examples from Axiom that have direct conversions to
Sage.
(I've cross-posted to sage-devel and sage-edu - sorry for the noise if
you read both.)
