A discovery layer is a resource discovery platform that provides a unified search experience across a library's collection, integrating various materials and systems through a single interface. It enhances user search capabilities with features like federated searching and expanded options while clarifying what it is not, such as being a complete replacement for existing systems. The discovery layer aims to improve searching efficiency and user engagement in libraries.
