I am a college student, using this site as part of a class project. I choose this site because I wanted to educate myself on something I knew nothing about. I thought the site had a very nice interface, whose graphics and organization of material made navigation easy. Small, organized blocks of text are much less intimidating to read than solid pages of text. Each topic and sub-topic is separately organized, but very easy to find, in case you need to easily find something particular. Some key words on the site are linked to pictures offering examples. I found this very useful, and only wish there could have been more of it. The site doesn't offer the most extensive information on the subject, but summarizes the key points. You can educate yourself on all the aspects of Mongolian rule in China in a short span of time. So, obviously, the only thing lacking would be more detailed and more referenced information (although there was quite a bit of referenced information on the site). If you aren't satisfied with your Mongolian education after perusing this site, you can always go elsewhere - the site, in fact, helpfully links to other useful sites and books regarding the specific topics found here. This site is just a taster, and I think ideal for students first exploring the topic.
