Reading Through History is a tiny entity which represents the efforts of two classroom teachers in the state of Oklahoma. We offer a significant amount of free content on YouTube, which we create in our own "free time". We're glad that you use our videos in your classroom, and we will continue producing more of them as time will allow. If you would like to, and if you have the financial resources to do so, please feel free to give any amount that might help us continue our efforts. Thank you.
