Chat With a Librarian

Chat With a Librarian is a live, online reference assistance chat service. Questions are answered by reference librarians participating in our worldwide network. This free service is easy to use and available 24 hours a day, 7 days a week. A microphone is not mandatory to use the chat service, as it is text-based. The service does allow for screen sharing if a student prefers that type of assistance and has a microphone.

If you’re not ready to connect with us yet, your question might already be addressed in these Quick Answers for Students. You’ll find videos and written instructions about how to start your searches, how to organize your results, and how to cite your sources. You will also find a list of answers to the questions students frequently ask.
