“Notabilia” is a special way of saying “things worth noticing.” On a large, historical scale, we can say that notabilia of the 20th century includes the two world wars, the Wright brothers’ first aircraft, Einstein’s theory of relativity, and countless technological advancements. But “notabilia,” which comes from the Latin “notabilis,” meaning “worthy of note,” also can apply on a personal level. Perhaps you keep a box of all the greeting cards you receive, or you notice the morning sun is especially warm one day and you stop to enjoy it. Notabilia is an extremely relative concept.
