Provide an e-book link to my textbook?
I have a textbook, published by Oxford, that I've put up on-line at http://pages.physics.cornell.edu/~sethna/StatMech/EntropyOrderParametersComplexity.pdf. (They haven't given me permission, but my editor knows it is there and isn't complaining.) I'm not sure whether it is OK for you to include it in your e-book listings, but I'd be delighted.
[Admin] Thank you for the suggestion, we will look in it.
