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.

UniTime

UniTime is an open-source academic scheduling platform designed to solve the complex logistical challenges of higher education institutions. You can coordinate course timetabling, manage student sectioning, and organize examination schedules while accounting for specific constraints like room availability and faculty preferences. The system uses advanced optimization algorithms to ensure your schedules are efficient and conflict-free.

You can also manage event room reservations and track departmental requirements through a unified web interface. Because it is open-source and based on the Comprehensive Academic Scheduling System, you have the flexibility to host it on your own servers and customize it to fit your university's unique administrative workflows. It is particularly effective for large universities managing thousands of students and diverse course offerings.
