What is Realia? I came across it while working through my Librarianship studies as an area of the Library collection. A library houses many different things other than books including videos, posters, manuscripts and a thing called Realia.
According to Wikipedia: http://en.wikipedia.org/wiki/Realia_(library_science)
“In library classification systems, the term realia refers to three-dimensional objects from real life such as coins, tools, and textiles, that do not easily fit into the orderly categories of printed material.”
