The document discusses library services for mobile devices at NIE Library. It introduces strategies used to develop a hybrid mobile application called LibGO! that provides access to library services on smartphones. A mobile task force was formed to review the library's mobile strategy. LibGO! was developed using a hybrid approach combining a native front page and web-based subsequent pages. This allowed for native functionality while keeping content updates simple. The application was successfully launched for iOS and Android, achieving the goals of convenience for users and increased usage of library resources without overburdening staff. Future plans include analyzing usage, gathering feedback, and enhancing LibGO! based on trends.
