Welcome to Talessman's Atlas of World History! I'm Thomas Lessman, an amateur historian with over 20 years of experience researching world history and a passion for history maps.
I appreciate "open resources" like websites, freeware programs, open-source software, and community projects. They provide greatly needed resources that are often too expensive on my limited budget. Even more important, they encourage people to work together for the common good instead of competing for profit. Out of respect to resources that have helped me over the years, I'm returning the favor the only way I can - by sharing my own work & knowledge!
