It's handy to keep by my quiet time/study area where I can refer to it as I'm reading. It's 18 inches tall (so it doesn't fit in the bookcase, for sure!) and opens accordion-style to about 17 feet. It provides a visual representation of over 4000 years with charts, maps, lists and chronologies. You can see who's living and what's going on in the known world during the same time period.
If you've wanted to connect the dots in biblical history, the Time Chart of Biblical History would be a great addition to your own home library.
