Now, you can login to the system using your campus login and password. This is your DUID number and your Passcode. After you login, you can then tag your books. For example, faculty can mark the books they recommend for classes using a class number, such as Chem101 or INTS4999. Students can tag books by genre. Groups of people can mark books relevant for a group project. One can also easily limit by the format that is needed. Looking for a DVD? Easy, just limit your search to DVD/Video using the "refine" area on the left hand side.
