What would it have been like to sit in Archibald Alexander's class on Systematic Theology in the early days of Princeton Theological Seminary? Fortunately, Princeton has scanned in Charles Hodge's notes from that class - just think, if you had been sitting next to Charles Hodge and snuck a peak at his notes, this is what would you have seen. It's a remarkable thing that we have these, but I'm sure there are many other manuscripts of classroom lecture notes (and professors' lectures!) holed away in archives around the country. If you know of any others that are accessible online, please let us know!
