Excessive reverence or worship of books; the practice of treating books as sacred or supremely important objects.
From biblio- (Greek biblion 'book') + -latry (Greek latreia 'worship, service'). Created in the 19th century alongside similar '-latry' words (idolatry, heliolatry) to describe book veneration.
Bibliolatry has a serious side: throughout history, controlling which books exist and circulate has been about controlling minds—so some societies literally did treat books as sacred objects worth protecting or destroying.
