>>In the Greek section of Strong's Concordance : Greek word # 975 "book" means a roll.
English word 'roll' comes from Latin 'rota' meaning wheel. >>

In those days, books were long rolls of papyrus or animal skins ...... that rolled up to form a scroll. The hebrew word for scroll is megillath sepher which means "roll of the book" and comes from the root word galal meaning to roll up. In Hebrew a library is called a house of rolls.
