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.

Famous quotes containing the words national, science and/or library:
“National isolation breeds national neurosis.”
—Hubert H. Humphrey (1911–1978)
“There are two kinds of truth; the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art.... Without art science would be as useless as a pair of high forceps in the hands of a plumber. Without science art would become a crude mess of folklore and emotional quackery.”
—Raymond Chandler (1888–1959)
“With sighs more lunar than bronchial,
Howbeit eluding fallopian diagnosis,
She simpers into the tribal library and reads
That Keats died of tuberculosis . . .”
—Allen Tate (1899–1979)
