An album (Latin: albus, lit. 'white'), in ancient Rome, was a board plastered with chalk or gypsum, or painted white (tabula dealbata), on which decrees, edicts and other ephemeral public notices were inscribed in ink using a calamus (reed pen). Album was an early predecessor of bulletin boards. In medieval and modern times the meaning of the word album had changed to refer to a book of blank pages in which verses, autographs, sketches, photographs and the like are collected. An ancient Greek equivalent was called leukomata (Ancient Greek: λεύκωμα pl. λευκώματα).
