4.2 The information timeline
Another difference in popular, professional, and scholarly sources lies in when information appears in these types of sources. Information about an event or issue appears in publications according to a predictable pattern known as the information timeline. Familiarity with the information timeline can help you best plan your research topics and where to search for information. For example, it typically takes several months to years for information about an event or issue to appear in scholarly publications. If you choose a topic that is very recent, you may have to rely more heavily on news media, popular magazines, and primary sources (such as interviews you conduct) for your research.
