“Abstract: All libraries in a community are interconnected, and if library users are unable to access the services of one particular library, then the other libraries in that community will inevitably have to take the strain. Jim Rettig, president of the American Library Association, describes this interconnectedness as the “library ecosystem,” and notes that all types of libraries must come together and advocate with a unified voice to survive and thrive in the modern world. Rettig’s plan for libraries to develop statewide coalitions that will advocate for all types of libraries is discussed.”
