Creativity requires input, and that’s what research is. You’re gathering material with which to build. -Gene Luen Yang
As you process all the great sources you found, consider using research organizers like diigo.com, zotero.org or mendeley.com, where you can keep all of your research in one place, including your notes on your sources. These sites will also help you with your citations.
When you have amassed enough information and organized it all, it’s time to write that essay!
