Overview

Atriuum

Atriuum is a comprehensive library management system designed to move your entire collection to the cloud. Whether you manage a K-12 school library, a busy public branch, or a specialized academic collection, you can handle circulation, cataloging, and detailed reporting from any web browser. You can easily track items, manage patron accounts, and perform full inventory audits without being tethered to a specific desk or server.

The platform focuses on accessibility, allowing your patrons to search the catalog and reserve books from their own mobile devices. You can automate overdue notices and manage fine collections, which frees up your staff to focus on community programs rather than manual paperwork. It scales effectively for single-building libraries or large multi-branch districts that need a centralized database for shared resources.

The app uses the same gamified approach as the main Duolingo platform, keeping children engaged with rewards and progress tracking while they master essential literacy skills.

You can trust that your child is learning in a safe environment because the app is completely ad-free and contains no in-app purchases. It is designed specifically for kids aged 3 to 8, including those in preschool through second grade. Whether you are looking to supplement school lessons or start a head start at home, the platform provides a structured path toward reading confidence.
