Idle Library

Idle Library is an incremental clicker about growing a small book collection into a vast archive. You start by cataloging books by hand, then hire librarians, digitize archives, open new wings and fund research to speed up growth. You can optimize upgrades actively or leave the library to progress while you are away.

Grow the library

Invest in upgrades to improve cataloging efficiency and automate book acquisition. Special collections unlock global income multipliers, helping turn a small reading room into a sprawling archive of rare manuscripts, ancient tomes and legendary codices.

Research and progression

Research Points unlock permanent upgrades across multiple knowledge paths. You can reduce research costs, improve production and specialize your growth strategy. Renovating the library resets your progress in exchange for permanent bonuses; each prestige level brings further opportunities for growth and optimization.

Quests and events

Daily objectives and achievements reward you with boosts and new strategic choices. You can host Book Festivals and take part in limited-time events for temporary boosts, or use Time Warps to simulate hours of growth instantly.

Customize your archive

Unlock and apply visual themes to change the look of your library.
