(CNN) — In case you needed an excuse to sit down with a novel or classic piece of literature, today is National Book Lovers Day!
This day is observed every August 9th and occasionally on the first Saturday in November.
Long before the days people could get e-books on Kindles and Nooks, books first were made of calf skin or parchment paper for pages.
Original book covers were created with wood and usually leather covered.
Public libraries have long been popular, making their debut during the Middle Ages.
