The library has a collection of noncirculating books that cannot be borrowed.
Noncirculating → It is formed from "non-" (meaning not) and "circulating" (from Latin "circulare", meaning to move in a circle). The word "noncirculating" means not moving in a circle or not being in circulation.
Think of 'not' ('non-') moving in a 'circle' ('circulare') — that's why noncirculating means something that is not in circulation.
