**DEEP INTERCONNECTION, INTERCOMPARISON AND RE-USE**

Since 1960, we have fought for a world of deep electronic documents-- with side-by-side intercomparison and frictionless re-use of copyrighted material.

We have an exact and simple structure. The Xanadu model handles automatic version management and rights management through deep connection.

Today's popular software simulates paper. The World Wide Web (another imitation of paper) trivializes our original hypertext model with one-way ever-breaking links and no management of version or contents.

**WE FIGHT ON.**
