Why do you think it's important that authors and content creators protect their intellectual property?
Intellectual property protection and copyrights are important because ideas often translate into a person's means of living. Capitalist society can't survive unless the individual has protection over their ideas.
What steps can you take to protect your own intellectual property or copyrights?
As the book says, you can post a copyright notice on your work, especially if its online. The notice must include the title of the work, the copyright symbol and year, and your last name.
What steps can you take to make sure that you cite the work of others ethically?
If you ever use something that wasn't originally yours, you have to cite it. Depending on the style you chose, the citation will look differently. But typically the author's name, the title of the work, where the work is published, who published it, and when it was published are included. A bibliography will feature the full citation, while in-text parenthetical citations point out specifically what information you borrowed.
