Long before books lived on shelves, they may have lived on trees: the Germanic ancestor of book, *bōks, is connected with the beech tree, whose smooth wood could serve as a writing surface for runes. English inherited bōc from Old English, while Latin took a different botanical route: liber, “inner tree bark,” eventually gave English library. The case half comes from Latin capsa, a box or receptacle, traveling through Old Northern French casse before reaching English; it is a different word from case meaning “an event,” which comes from Latin casus, “a falling.” By 1726, English speakers had simply fitted the two pieces together: a book-case was a box-like piece of furniture built to hold books. So a bookcase is, in a surprisingly literal sense, a wooden home for objects whose name still whispers of beech trees and bark.
