So I've been studying French for a few years now and I've decided that translating an old French math paper into English would be a good exercise to further improve my French competency. I would also like to translate a paper that hasn't already been translated so that my work might be useful to someone somewhere.
I was wondering if anyone knows of a good source on the Internet to find old French math papers, something in algebra/algebraic geometry would be preferable and the older and more elementary the better, as I'm certainly no mathematician (yet).
Have a look at the Euler Archive, which contains all 800 articles of Leonhard Euler, in his many subjects of interest.
Most of the articles are written in Latin, but some are in French and have not been translated yet. In fact, they are even looking for translators!
