Modern Library

The Modern Library is an American book publishing imprint and formerly the parent company of Random House. Founded in 1917 by Albert Boni and Horace Liveright as an imprint of their publishing company Boni & Liveright, Modern Library became an independent publishing company in 1925 when Boni & Liveright sold it to Bennett Cerf and Donald Klopfer. Random House began in 1927 as a subsidiary of the Modern Library and eventually overtook its parent company, with Modern Library becoming an imprint of Random House.
