Realia

[ray-AH-lee-uh] /reɪˈɑːliə/

Realia is a library term for three-dimensional objects like textiles, tools, and coins that fall outside the typical library classification system. Ned Kelly's armour is the best-known piece of realia at State Library Victoria, but there are many other examples within the Library's heritage collections, preserved for their association with notable people and events in Victorian history.
