is there a tutorial on how to use the library
Were you looking for anything specific in terms of using the Online Library? A specific database or resource?
You can find a variety of video recordings and print tutorials to walk you through using the Online Library under the Tutorials and Guides button in the Online Library. I would recommend starting out with the Tour of the Online Library, listed under the Library Instruction Webinars. This will give you a general overview of the Online Library.
Please let us know if you have any other questions!
