Every day, newsworthy events happen: scientific discoveries get made, there's a traffic jam downtown, a new business opens or an unfortunate crime occurs. We usually first hear or read about these events from news sources such as the radio, television, news sites on the internet or a newspaper. Even when we learn about newsworthy events through social media sites it is often through a link to a professional news source.
Particularly noteworthy events that capture our attention such as a political scandal or horrific crime may end up in popular magazines like Time or Newsweek. More significant events like wars, political movements, or major scientific discoveries get discussed over longer periods of time and may capture the attention of academics who write about them in scholarly journals and books. Eventually, many of those events end up in reference sources like encyclopedias.
