When it comes to visually presenting and understanding key dates and events in one's personal life or in world history, timelines can be very useful. Online tools to facilitate their creation, however, are not always easy to come by or intuitive to use. With a free "Lite" version, Preceden allows readers to make timelines in minutes, using a number of adjustable templates. Signing up is easy and versions are available for educational, business, or personal use. Timelines are private by default, but may be freely shared on the web for those who would like to publicize their information. Whether used for a student project or as a teaching aid, one can imagine many innovative uses for this web-based timeline maker.
