This document provides an overview of WorldCat Navigator, a system that allows libraries to share their collections. It explains that Navigator creates a single catalog for a consortium of libraries, allowing users to search all collections at once and request items from any library. The workflow for item requests is described, showing how Navigator streamlines the process compared to traditional interlibrary loan. Implementation of Navigator involves preparation, configuration, testing, training, and a go-live phase. Overall, Navigator aims to give users broader access to materials while making resource sharing more efficient for libraries.
