This document summarizes the recommendations of the DLF ILS Discovery Interface Task Force regarding opening up the integrated library system (ILS) to allow for improved patron discovery and delivery through external applications. The task force analyzed problems with current integration and proposed a technical recommendation specifying core functions and bindings through an application programming interface (API) to better support discovery, delivery, and patron account management across systems. The document outlines the membership and process of the task force and provides details on the proposed API functions to facilitate feedback and future implementation efforts.
