The term 'library-contained' is a compound word formed from 'library' and 'contained'. 'Library' originates from the Latin word 'librarium', meaning 'a place for books', and 'contained' comes from the Latin 'continere', meaning 'to hold together'.

'Library' evolved from the Old English 'librarie', while 'contained' developed from the Middle English 'contenen'.

Initially, 'contained' meant 'held together', but in this context, it evolved to mean 'self-sufficient within a library'.
