Excellent Resource for Biblical Studies

This past Sunday I decided to begin reading through all the OT Prophets in chronological order. I've kept a chart for years that details each Prophet's

• years of ministry (estimate)
• primary audience
• ascendant world power
• relationship to Northern and Southern Kingdom exile

I wanted to update this info and was googling around for some sites and came across Dennis Bratcher's Christian Resource Institute.

I found their outline Survey of Old Testament History and Key Biblical Dates chart particularly helpful and thought I'd mention it here.
