Librarian droids in the Lost Library of Nelgenam.
Droids specialized for library work, which were also called archive droids or archival droids, were a specific droid model designed to operate within libraries. A librarian droid was responsible for the upkeep of the Ha Zurh Library and Records Office located in Tipoca City. Even centuries after its abandonment, numerous library droids could still be found within the Lost Library of Nelgenam. When the cartographer Emil Graf made an attempt to enter the library, two library droids confronted him and tried to kill him.
TR-33NA, an SP-4 analysis droid at the Graf Archive situated on Orchis 2, carried out this very function. At one point, an archival droid collaborated with Leia Organa, the former crown princess of Alderaan and the present-day leader of the Resistance, in order to produce her biography.
