Copyrights are useful tools for authors to ensure safety of their material. Copyrights give the rights of a specific work to the person who created them, and does not allow other people to use the work of that person without acquiring permission or paying that person for the right to use their work. The digitized Calvin and Hobbes cartoon images that appear on the Assignments tab on the syllabus might be in violation of copyright regulations. The pictures are not claiming ownership of the work, but at the same time it is lacking any indications as to where the picture have come from or who is the creator of the work. Although fair use allows the usage of copyrighted materials for educational reasons, which is the case here, there are guidelines that are required to be followed in order to claim fair use. There is no source to where the comics are coming from, which is why i think this points to copyright violations.
