The term 'library-based' combines 'library,' originating from the Latin 'librarium,' meaning 'bookcase,' and 'based,' from the Old English 'bæst,' meaning 'foundation.'

'Library' evolved from the Latin 'librarium' to the Old French 'librairie,' and eventually to the modern English 'library.' 'Based' evolved from the Old English 'bæst' to the modern English 'based.'

Initially, 'library' referred to a place where books are kept, and 'based' meant having a foundation. Together, 'library-based' has come to mean something that is reliant on or related to a library.
