The BILLI (Bibliographic Identifiers for Library Location Information) system is a Linked Open Data platform for organizing the classmarks used at the New York Public Library. By mapping together 19th, 20th, and 21st century classification systems, BILLI creates new connections between our resources and provides insight to staff and researchers how they are organized.
