I admit, I'm no expert on copyright.
After viewing several other blogs and skimming through some of our text, I wonder if I have made any copyright violations in my college or teaching days. (I hope not!) There are so many times I will run to make a quick copy or share something with my students or a colleague, and never think twice about copyright.
Hopefully, soon I'll have some basics up here for people like me, busy teachers (or busy people in general) who find something great and want to share it (without breaking any laws!).
