Quick note... Make sure you enter title, author, ISBN information for HI, DI, and DUO into Joy. The system is designed to TRY and avoid the same pieces being in a room for the first few rounds.
Please also don't forget titles for OO and INFO entries.
For POI, you don't need to enter anything, just bring a bibliography to to on-site registration.
Let me know if you need help finding where to do this.
