If you need reference assistance during times when the library is closed you can use Ask Here PA. This service provides you reference help 24 hours a day, 7 days a week. Ask Here PA can provide you with an answer to most reference questions within 15 minutes. In the case of more in-depth research, Ask Here PA will give tools to get you started, and offer you a referral to a Gumberg librarian during normal library hours 8AM-6PM.
Reference librarians have also designed Research Guides for many majors and courses of study that can help when a librarian isn't available.
