The Microfiche N-B collection is a set of microfiche titles that are not grouped into serial or subject collections. They are arranged by local N-B (Non-Book) numbers. You will need to have this N-B number in order to request the correct microfiche box from RooBot.
The title records will have the N-B number in a Note field. Once you have this number, click the link below in order to request the needed box from RooBot. You can then pick up the microfiche that you need from the Access Services desk.
