The Registrar's Scroll is a spool of parchment that registers the name of all school-age children (presumbly those in the Midwestern wizarding territory). It is kept in the Registrar's Office of the Charmbridge Academy, and records the names sent to it by the Central Territorial Census Office in Chicago. Thomas Bagby is the record-keeper in the department that transmits those names. In December of 2010, Quick again snuck into the Registrar's Office to consult the Scroll, searching for the names of Livia Pruett, Claudia Green, and Lilith and Diana Grimm.
