Public libraries in the lives of people experiencing homelessness. The number of Australians living without secure housing grows every year. Increasingly this community is reaching out to our public libraries for shelter, connection to others and access to resources and services. Despite this relationship, there are no public policies to guide libraries in supporting this community or in partnering with housing agencies. Using a process of participatory design with the homeless community, public library staff and users, and housing agencies, the research builds theoretical frameworks and public policy foundations to support the design of public library services, resources and environments that will meet the needs of the Australian homeless community in our urban, regional and remote contexts.
