My google-fu is weak
 

Anybody having any luck finding a web page that lists the founding dates of all 300+ Division I basketball schools?

Best I could find is:

NCAA Sports Sponsorship

Run the query and you'll get a list of links to the team sites I presume each will have their founding dates ...

(disclaimer - no idea what this list is so can't validate its the right one)

It's a little round about, but College basketball - Wikipedia, the free encyclopedia will give you a list of all the ocnferences, and it appears each conference wiki page has each school's founding date.

We're #2, We're #2!

Also, here is a list of all of the schools and the year they started being a member of the NCAA (or years they were members, if no longer a member)

Thanks, guys. :)
