Philippine libraries hold rich, distinct collections — but they've historically been searchable only one at a time. Union Catalog Philippines curates and unifies those holdings into a single, shared catalog built for education.
Curated Collections
We work with academic, public, special, and national libraries to bring their catalogs into one consistent, well-described record set.
Unified OPAC
One search interface across every participating institution — find a title once, see exactly which libraries hold it and how to access it.
Built for Education
Designed with students, faculty, and researchers in mind, supporting thesis research, instruction, and lifelong learning nationwide.
