From Cornell University's online publication of the Public Law.
§ 107. Limitations on exclusive rights: Fair use
Now I am just confused. IF the author published the picture as an employee of a Government agency, it can be reproduced. If the photo uses the copyright seal and it is properly identified and not used for profit, is it fair use? I am pretty sure that my use did not substantially diminish its value and I damn sure not going to profit from it. It is intended for non-profit educational use to demonstrate what the buggers look like. What do you think? Does anyone care?
Added Note - The photo of the Ticks was from an Iowa State online reference work. I really think I'm OK here but I'm still waiting for the other shoe to drop. MUD
