The Digital Library for Earth System Education (DLESE) is a community-owned and governed digital library offering high-quality electronic resources that foster learning about the Earth at all educational levels. When fully operational, DLESE will offer peer-reviewed teaching and learning resources, interfaces, and tools to allow exploration of Earth data, services to help users effectively create and use educational resources, and an 'intellectual commons' facilitating sharing, collaboration, and excellence in Earth system education. DLESE users include learners and instructors in all venues, many of whom are also resource contributors, developing educational materials, providing scientific knowledge, and evaluating DLESE holdings. To date, significant progress has been made on many aspects of the library: the community has been organized, a governance structure has been established, a Strategic Plan has been developed, a useful collection is available, and a working version of the library is now in use.

As our library-building processes have matured, two highly prioritized community goals are in the process of coming on line: a DLESE Reviewed Collection and a community collection-building tool. The purpose of the Reviewed Collection is to help library users find quality, peer-reviewed teaching and learning materials and to provide a forum through which electronic resource creators can achieve academic career recognition. The purpose of the community collection-building tool is to enable library users to develop and manage local digital collections so that these collections can eventually be shared with others. This presentation will review the progress to date on both of these community priorities. In addition to collection building, linkages to other digital libraries, like NASA's JOINed Digital Library, will be highlighted.
