'library-related' originates from the word 'library,' which comes from the Latin word 'librarium,' meaning 'a place for books.' The suffix '-related' is used to indicate a connection or association.

The term 'library' evolved from the Latin 'librarium' through Old French 'librarie' and eventually became the modern English word 'library.' The suffix '-related' is a modern English addition to form compound adjectives.

Initially, 'library' referred to a place where books were kept, and 'related' meant connected. The compound 'library-related' maintains this meaning of association with libraries.
