The document discusses various challenges facing libraries in preserving collections over time, including natural disasters, deterioration, lack of space, and issues with digital preservation. It outlines responses such as collective physical storage facilities, digitization efforts, collective digital repositories, and efforts to increase exposure of collections through tools like union catalogs and WorldCat. However, it notes many digitization efforts are inadequate in scale and do not guarantee long-term preservation. Central questions are raised about whether current approaches are comprehensive enough to truly address the preservation challenges libraries face.
