First of all, don't panic! Research is difficult and nobody expects you to know how to do it all on your own. Check with your teacher if you aren't sure how to approach your assignment or want a second opinion on sources and strategies.
In the library, visit the Reference Desk (Library, main floor) and let us know how it's going. We're sitting there for a reason. Unless we're helping someone else, whatever we're doing is just killing time waiting for your questions. Don't be embarrassed - even seniors writing their theses ask us questions!
