With truth and accuracy being the lifeblood of nonfiction, it is crucial that the writer get the facts right. There are a number of means to accomplish this, most or all of which you will use at some point in your work. Some of these methods have specific protocols such as research and interviews while others, like relying on your own personal experiences and observations, are less formal. You also need to know what pitfalls to avoid, such as copyright infringement and consulting experts who are not what they appear to be.
