In addition to what I have already addressed, I will just add that if you want to include archival work in your courses, you need to work closely with your librarians. Before you assume that students can have access to any rare materials, or that they can take notes on a rare book, or compare multiple manuscripts, check your special collections’ policies. And before you assume that your library does or does not have material relevant to your course, talk with the librarians. You might be surprised to learn that some books are too fragile to be handled, for instance, or that there is a large number of books relevant to the history of science in the 1700s. No one knows a special collection better than its librarians, and they are your first resource and your first ally in making archival work relevant to your curriculum.
