Librarians offer in-depth research help.
During library open hours, ask at the main desk for help finding what you need. The desk is usually staffed by student workers - if you have in-depth research questions, just let them know that you want to meet with a librarian.
Click on the Ask a Question tab on the right side of a library web page. It will bring you either to live chat, or to a place where you can leave a message.
