The fifth and final step in Information Literacy is to ethically use the resources you have gathered in your paper or project. This means that you need to correctly cite them both in the text of your paper and in your references, works cited, or bibliography.
Even though information, words, and ideas are not concrete, they still can be stolen by them not being cited and those who commit plagiarism get in trouble.
Ethical use of information means using information ethically. Clear as mud, right? Actually, there are two ways that very clearly deal with this concept. They are plagiarism and copyright. Both deal with giving credit where credit is due and using other people's work correctly. Even though information, words, and ideas are not concrete, they still can be stolen and those that do that can still get in trouble.
This is a serious but humorous explanation of copyright.
