About the game
Build the greatest library the world has ever seen — one book at a time.
Idle Library is a relaxing incremental clicker where your humble collection grows into a vast archive of knowledge spanning rare manuscripts, ancient tomes, and legendary codices. Start by cataloging books by hand, then expand your institution by hiring librarians, digitizing archives, opening new wings, and funding cutting-edge research to accelerate your growth.
Whether you're actively optimizing your upgrades or letting your library grow while you're away, progress never stops.
