Copy-What?

I think that there are a lot of teachers that forget about the copyright law. I forget sometimes, too.
We can use so many resources, but to avoid trouble we need to be sure we have permission to use the material. Once I read about all of the dos and don'ts I realized that it is actually quite easy to ask permission. On the otherhand, it adds another thing to the endless To Do list. I do like that public domain info is available for any educational purpose.
