What is a proxy card? Where do you get one? (LC Desk?)

A proxy card is a card a student can get when they do research for a professor. It basically gives the student permission to take out books under the professors name. That way they are not responsible if a professor does not return a book, the professor is held accountable. You are correct to send them to the LC Desk! They can get all of the details and instructions there. They can also get most of that information online here... http://www.library.umass.edu/services/borrowing/application-forms/proxy-card-application/
