The familysearchindexing.com site has recently put up the Aguascalientes section of the 1930 Mexico census up as a project!

Given that most people in this group are computer saavy and that this state is smack in the heart of our area of research, we should try to get as many people involved in helping out with this indexing project. You can volunteer to index as little or as much as you want and you can do it anytime you want over the internet.

Sign up for an account and start indexing today! I just did a couple of batches and it was quite simple.
