This was one area of Forensics that always left me intrigued. You come to the tournaments and you see that every team has a thousand files stuffed into 3 or 4 boxes. I was always left with the same question in mind: "How do they keep all of that straight?" Although extemp is an individual event, it is imperative that competitors realize that filing and organization is a team effort that comes to the benefit of each and every individual involved.
So how do you organize extemp boxes? The easiest way is by topic. If you alpabetically arrange your files by category, it is important to balance the strength of each area. You shouldnt have a million folders covering every possible topic from aa lava to ZZ top. But at the same time, you shouldnt have seven categories (one for each continent). It is important to highlight the major areas. Look at the news. Have a file for Iran, Iraq and Afghanistan. For domestic issues, have a file each for Cap and Trade and Healthcare. Some of this is obvious. And when you create these files, keep them organized for your sake and the sake of your team.
Ways not to organize? Dont organize by source. Dont have files for the Christian Science Monitor, Newsweek and the Wall Street Journal. Although resources make your speech more authoratative, this can be confusing and take precious time from your organization.
