"Hello, class. Today I shall reveal to you the hidden magic of everyday books. And I don't mean the 'magic of reading' or any such nonsense. I'm speaking, of course, of Bibliomancy. Let's start at the beginning... Thanks to Bibliomancy, every book can be about you."
Sybill Trelawney introducing Bibliomancy to her students[src]

A book used in Bibliomancy

Bibliomancy was a branch of divination that involved opening a book on a random page, in order to interpret its contents in a contextual way, or to adapt its meaning to the present time.[1]


During the 1989–1990 school year at Hogwarts School of Witchcraft and Wizardry, Professor Sybill Trelawney taught her sixth year students about the art of Bibliomancy in Divination class.[1]
