I have a suggestion for the site. I think it would be great to have a “Reading List” page where you and the other faculty can recommend books to read for further information on various topics. I know that there are “suggested readings” that accompany many of the lectures, but sometimes it can be cumbersome to try and recall which lecture the topic you are interested in was on, and find the appropriate reading. Also, the suggested readings can sometimes leave out some critical (or just interesting) topics.
Rather than coming to the forums and asking “Can you recommend a book on X?”, it would be great to have a page sorted by topic where you could scroll to “Thomas Jefferson” and see recommended biographies or scroll to “The French Revolution” for recommended books on that. I love reading books on history, but it can be difficult when ordering from amazon or in a library to determine which books are legitimate, and which are merely propaganda.
