Sometimes a Web page off-site — or a passage in a book, for that matter — answers a question perfectly. How should I refer to or quote that external source as my answer?
The community has generally accepted this as site policy on Mi Yodeya:
Frequently, an answer to a question on this site, or information that can contribute to an answer, is available verbatim on some other website or in print. This guideline addresses how the responsible user should make use of such external content.
Please comply with this policy in all of your posts on this site. We are not lawyers, but our understanding of American copyright law is that copying entire pieces without permission, even with attribution, is a violation of the original author/owner's copyright. In addition, we feel that it's just not fair for this site to use other people's work to drive traffic to our website rather than to the original author/owner's.
