About this 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.
Grow Your Collection
Turn a small reading room into a sprawling knowledge empire. Invest in upgrades that increase your cataloging efficiency, automate book acquisition, and unlock powerful global income multipliers through special collections.
Research & Knowledge System
Earn Research Points to unlock permanent upgrades across multiple knowledge paths. Reduce research costs, enhance production, and specialize your library’s growth strategy to reach new milestones faster than ever before.
Prestige & Long-Term Progression
Renovate your library to reset your progress in exchange for powerful permanent bonuses. Each prestige level opens new opportunities for exponential growth and deeper optimization.
Daily Quests & Achievements
Complete daily objectives and earn achievements to gain rewards that accelerate your progress and provide new strategic choices.
Events & Time Warps
Host Book Festivals and participate in limited-time events for massive temporary boosts. Use Time Warps to instantly simulate hours of growth and push your library to the next level.

I made a new game - The Night Librarian 🕯️
Hi everyone,Thank you for playing Idle Library - it's meant a lot to have so many of you spend time with a library game I made. I've been working on something new, and I wanted to share it with the people who supported the first one.I also want to be upfront about something. A lot of you gave honest feedback about AI-generated content in Idle Library. I heard you, and I took it seriously - The Night Librarian contains no AI-generated content. The writing and artwork are entirely my own.It's a different kind of game from Idle Library - a cozy mystery puzzle game (though I clearly couldn't stay away from libraries). You play the night-shift librarian at Ashwood Library: sort the returns, find the books patrons are after, and set the shelves right before morning. But the longer you work, the more you notice the library isn't quite… empty. Across five nights, a mystery unfolds.No timers, no pressure - just you, 22 hand-made puzzles, a candlelit library, and a mystery that slowly gets under your skin.It's coming to Steam this July at $2.99, and wishlisting it now genuinely helps me have a real launch as a solo dev:👉 Wishlist The Night Librarian on SteamThank you - for playing the first game, and for giving this one a look.- DaZeSTRAYRead full article on Community Announcements (DaZeSTRAY)Patch NotesOfficial
