Students often believe common myths regarding copyright.
Unfortunately, these broad statements are not the case much of the time. Unless you can determine otherwise, assume everything is copyrighted.
Not all images found on the internet are free for the taking. Students should investigate the copyright status prior to using an image. Just citing an image is not enough.
Students can use the Library's ImageQuest database for copyright cleared images.
Google Image search has a feature that allows users to limit their search based on usage rights.
Sharing copyrighted material by posting it to websites, including social media, even those behind a password (such as Moodle) should be avoided. Linking to online material (authorized by the copyright holder) is recommended in lieu of digital copies.
