Prior to my teaching career, I used to study Medieval and Early Modern History, so please forgive me this post.
The Chronicle of Higher Education's Wired Campus has a story about the Catalog of Digitized Medieval Manuscripts. So far, there are 5,000 manuscripts available. As more of these texts get digitized, the ability to research is going to get infinitely easier. While there is undoubtedly a romantic allure in sitting in a musty archive or library in foreign lands, this new availability makes it easier for cash-starved scholars to complete their work.
