Books and articles can provide you with more in depth information about your topic. Book-length works may be broader in scope, while articles tend to focus more narrowly on a specific aspect of a topic. Aside from being shorter and more focused, articles are also a good source for the most up-to-date information as they are published more frequently than books. Don't let books' length scare you away, though! Sometimes you'll find a book that contains a chapter or two on the topic you're researching and that's all you'll need to read. Using a book's table of contents and/or index can help you target the parts that are most relevant to your research.
