In this chapter we first discuss the proofreading process in general. We then provide a list of the common marks used in proofreading and examples of how to use them.

Proofreading is an acquired skill, and, as with any such skill, it takes practice before you develop an eye for catching all of the errors that can crop up in a document. Proofreading is also a process in that you can develop a series of steps to make the task both more effective and more efficient. The following steps can help you to produce error-free documents:

It is easy-too easy-to read what you think you wrote; you are much more likely to see errors if you can get away from your writing for a while and then look at it again. Also, if your document is long, take some breaks during the proofreading process-both the brain and the eyes can tire quickly during the task.
