OpenRS and ReShare are both open source resource sharing platforms that share a common code base as an ancestor. ReShare’s focus is primarily on ISO18626 interlibrary loan transactions and providing a stand alone interface for use by patrons and library staff to manage transactions. OpenRS is focused on the spectrum of resource sharing methodologies, incorporating workflows that accommodate various levels of mediation by library staff. This includes direct consortial borrowing for handling resource sharing at scale within and between consortia. OpenRS integrates directly with multiple ILS/LMSs and Discovery products, eliminating the need for a stand alone interface.
