copyright in the classroom....

After having read through a number of websites regarding copyright, I have the following observations: first, I was entirely unaware that my creations were copyrighted; second, I now understand why my professors are so restricted in the length of photocopied sections from texts or even sections of texts that are available to students electronically (e-reserve); and finally I am thankful for these resources regarding copyright rights so that I can avoid getting ensnared in unintentionally violating copyright laws when I am in my own classroom. Good stuff....
