If you work at all with images - and all of us do, right? - you'll need to know about copyright and fair use. If you're not a lawyer and steeped in the details of the law, you'll likely find reviewing the issues every few months to be helpful. Here are a few sites with clear and succinct explanations: Copyright and Fair Use and How it Works for Online Images from the Social Media Examiner The Digital Image Rights Computator from the Visual Resources Association Tales from the Public Domain: Bound by Law? a free digital comic book from Duke University's Center for the Study of the Public Domain Of course, we at Imageworks and at the University Library's Copyright Office are quite happy to help you out as well!
