Libraries have been at the heart of educational institutions for centuries. Today, digital libraries provide essential support for teaching and learning.

They also learn by doing, and share their creations, including reports, theses and dissertations. Teachers share courseware,
including demonstrations, simulations, datasets, lecture notes, exercises, and test sets.
