    You might want to add to your references an obvious one(which I am too modest to name !) listed in the wiki

    Sorry for not having added the link earlier. I did have it at characteristic class and Pontryagin class, now I copied it over to Chern class, too.

    If you see it missing elsewhere, please just add it. As opposed to Wikipedia, on the nnLab you may be non-modest, if only it helps spread useful information.

    Yes, the nLab is our lab notebook, and we may wish to make note of where our papers are relevant to material in our notebook.
