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.
