Ohio libraries are seeking a solution provider for a hosted (SaaS) or integrated online event calendar system tailored to the needs of multi-branch library systems. The desired platform must enable library staff to efficiently manage, promote, and track attendance for events spanning multiple locations, while accommodating distinct tenants for each library organization and offering tiered user privileges.

Key requirements include a mobile–responsive public calendar with multiple viewing options (list, grid, and monthly), comprehensive filtering by age group, event type, or location, and a seamless registration process for patrons. The system must support waitlists, automated email or SMS reminders, and attendance caps to ensure efficient event participation. Library staff should benefit from an intuitive dashboard for creating and managing events, handling registrations, and generating attendance reports.

Branding and integration capabilities, such as event feeds, custom CSS to match library websites, and optional API or widget-based embed functionality, are essential. Of particular note is compatibility with Drupal-hosted sites, as maintained by OPLIN. Additionally, the platform should offer an optional integrated room booking module, allowing patrons to reserve study rooms or community spaces according to individual library policies, with separate pricing for this feature preferred.
