The Library of Congress is open to the public. Visitors can freely read most of the books and other materials in the collection. You will generally have to travel to the actual library; only a limited subset of their collection is available online.

We've built this amazing "internet" technology to enable readers all over the world to read things, removing many of the limitations of physical books.

We should make better use of it.

But think of the lost copyright fees!
