Availability of resources in other special collections libraries and archives this academic year will likely vary. Please check collection websites for up-to-date information on hours and policies on visitors. Digitized materials may sometimes be available. Libraries and archives will also often scan pages for a fee.

If you do have the opportunity to visit a special collections library, you will want to be prepared. It will likely require an appointment with a prior list of materials you need to see.
