This document provides an overview of FRBR (Functional Requirements for Bibliographic Records), including:
1. FRBR defines user tasks like finding and identifying bibliographic entities and provides a conceptual model of works, expressions, manifestations and items.
2. It describes attributes and relationships between these entities using the example of Newton's Principia.
3. FRBR is influential in cataloguing standards like RDA and the design of library discovery systems but has limitations around implementation and fitting non-text works.
