Check out these books in print and/or online for further reading on your topic once you've gotten started.
News, commentary, and organization resources are often helpful in identifying ideas, topics, or issues that may be of use to you as you develop your research question. These types of sources are considered "non-peer reviewed' meaning they are not vetted in the same way as articles in academic journals. As with any source, evaluate your information. See the guide homepage for evaluation tips.
