The United States' National Science Digital Library (NSDL) is an open-access online digital library and collaborative network of disciplinary and grade-level focused education providers. NSDL's mission is to provide quality digital learning collections to the science, technology, engineering, and mathematics (STEM) education community, both formal and informal, institutional and individual. NSDL's collections are continuously refined by an extensive network of STEM educational and disciplinary professionals. Their work is based on user data, disciplinary knowledge, and participation in the rapid evolution of digital resources as major elements of effective STEM learning.
Resource types available via NSDL include instructional matierals, activities, lesson plans, audio/video materials, images, web sites, simulations, visualizations, tools, and services. NSDL also provides annotation collection and paradata (usage data) collections: comments, ratings, or usage information attached to existing resources in the NSDL.

“The universe is the externisation of the soul. Wherever the life is, that bursts into appearance around it. Our science is sensual, and therefore superficial. The earth, and the heavenly bodies, physics, and chemistry, we sensually treat, as if they were self-existent; but these are the retinue of that Being we have.”

“To a historian libraries are food, shelter, and even muse. They are of two kinds: the library of published material, books, pamphlets, periodicals, and the archive of unpublished papers and documents.”
