My sister just told me about this learning disability newsletter. Here's a link to it - it has quite a bit of good info on ADD, OCD, Aspergers etc. Once you get to the website, towards the bottom is where you'll find the LD links.

This also led me to find this website:

It has lots of good videos and books on the various disabilities, although I would suggest you see if it's available through your library first.
Cool.
