book: [OE] Book is widespread throughout the Germanic languages. German has buch, for example, Dutch bock, and Swedish bok. There point to a prehistoric Germanic *bōks, which was probably related to *bōkā ‘beech’, the connection being that the early Germanic peoples used beechwood tablets for writing runic inscriptions on. The original meaning of the word in Old English (bōc) was simply ‘written document or record’, but by the 9th century it had been applied to a collection of written sheets fastened together.

Old English boc "book, writing, written document," traditionally from Proto-Germanic *bokiz "beech" (cognates: German Buch "book" Buche "beech;" see beech), the notion being of beechwood tablets on which runes were inscribed, but it may be from the tree itself (people still carve initials in them). The Old English word originally meant any written document. Latin and Sanskrit also have words for "writing" that are based on tree names ("birch" and "ash," respectively). Meaning "libretto of an opera" is from 1768. A betting book is from 1856.
