Etymology
From Middle English librarie, via Anglo-Norman librarie and Old French librairie, the word first records the Norman's taste for Latin vocabulary, in this case librarium, 'bookcase' or 'chest for books', lifted from librarius, 'pertaining to books', itself from liber, the book that began as stripped bark of tree. Proto-Indo-European leub(ʰ)-, 'to peel', supplies the root. The Old English term, bōchūs ('bookhouse'), disappeared some time after the imported romance term took root.
The continental cousins turned practical quite early; French librairie, Italian libreria, Spanish librería, Portuguese livraria, and even Romanian livrărie now mean 'bookshop', a retail sense imported by the 16th century. England alone kept the old meaning.
