Help with collection. Please

[negatorian]

Hello,

I'm a huge Baylor fan and have decided to start a collection of a card from every player that played for the university. This is a tough task since the university has been around since the 1800s.

Since I'm new to this, where would you guys suggest I go to find the harder to find cards? I'm hitting COMC pretty hard and looking on eBay, but there are several that aren't in either place.

And suggestions on other places to look?

Thanks in advance.
