This tool was shown at one of the session at the NCTIES conference. Xtimeline is a free web-based timeline for teachers and students. Take a look at this Xtimeline for Romeo and Juliet: http://www.xtimeline.com/timeline/Romeo-and-Juliet-timeline
Notice that students can choose to see the timeline as links to information or as more detailed information, as shown below, by changing the icon link in the upper right corner. Students use the scroll bar at the bottom to scroll through the timeline. The timelines can be printed by permission, but teachers and students can easily use Xtimeline from the web.
Xtimelines can be explored by categories, by keyword searches, or by lists.
