Using SparFun eagle and schematics designs

Hey.

I recently was given a few MEMS from a friend (for free) so I am looking into breaking them out. The schematics were easy for me to make off the data sheets but I am having trouble with the eagle design. I am wondering to what extent I can use the SparkFun schematics and eagle files.

Can I use them as long as I cite SparkFun as the creator? or can I only use them for reference?

Thanks!
