Think about an event like Hurricane Katrina for a moment. When this first occurred, information was initially available in news sources, like newspapers, news websites, and radio and television broadcasts. After a week or so, information on the event began to find its way into popular magazines and other sources of news analysis. A month later, information began to appear in professional magazines and more in-depth news reports and analyses. Six months later, articles in professional journals and conference proceedings began to appear. After a year or so, books, government reports and articles in scholarly journals began showing up in bookstores and on library shelves. Now, several years later, the event is the topic of a number of scholarly books and journal articles, and even reference works like encyclopedias include entries on the subject. ¹
