AB: Digital libraries have been identified in many reports and workshops as one component of cyberinfrastructure to not only support the aggregation and dissemination of materials, but as new architectures to support the development of networks of knowledge and understanding. The Digital Library for Earth System Education (DLESE) is aimed to support Earth system education, but is itself a component of a larger network of digital libraries in the sciences such as the National Science Digital Library (NSDL). These networks of libraries are envisioned to provide a "knowledge layer" over a broad array of heterogeneous components from data sets to learned articles, from data analysis to complex simulation environments. As cyberinfrastructure develops the tools and technologies to access and interact with data (for example in projects such as LEAD, GEON, THREDDS), the distinction between scientific data archiving, access and analysis, and the functions of a digital library continue to blur as we concentrate on the needs of the user, be they researcher, teacher or learner. Data analysis may be incorporated into more complex artifacts such as compound documents, simulation environments, and learning objects, which themselves must contain attributes and descriptions for understanding their context and use. Thus a cyberinfrastructure that incorporates the range of technologies of data access and analysis and digital libraries that can provide broad context must include mechanisms for interoperability through all levels of these infrastructures. New tools and approaches in digital library and information sciences can leverage the materials and relationships provided through this interoperability.
