This document discusses rethinking the library services platform (LSP) model to improve interoperability between systems. It notes that while new LSPs have emerged, significant lack of interoperability remains between components of the library technology ecosystem. The author argues that libraries should adopt a platform approach like Windows or Apple, where vendors provide tools and services to allow third parties to build applications on their platforms. This could encourage more applications and make platforms more valuable. Prioritizing the library user perspective may change how libraries think about LSPs. Standards bodies are working on interoperability issues but more remains to be done to fully integrate solutions.
