Mini-hint to help with editing: fact sheets

A client of mine recently told me about a technique one of her grad school peers uses to get a handle on all the information he's trying to incorporate into a chapter. He creates what he calls "fact sheets." Each fact sheet has one sub-topic or question at the top of a page, and under it he collects his notes and thoughts on that one topic. My client has been using this technique as she edits a chapter, and says that this helps her review her notes in a "somewhat orderly fashion."

How do you get a handle on all the information that is piling up in folders in your computer or on your desk? How do you make sure it all makes it into your writing?
