  1. thumb index

    A thumb index, also known as a thumb cut or a thumb notch, is a series of notches cut into the edge of a book, often a dictionary, directory, or encyclopedia, to allow quick access to particular sections. Each section would be marked with a tab that protrudes slightly from the edge of the book, and these tabs are arranged in a sequence to aid in locating information quickly. It's called a "thumb index" because it allows users to use their thumb to quickly flip to the section they're interested in.
