The Link is the magazine of Carnegie Mellon University’s School of Computer Science.

Its name recognizes the pioneering work of two of the School of Computer Science's co-founders, Allen Newell and Herb Simon, who invented the use of linked-list data structures for representing complex information.

But it also serves as the link between the School of Computer Science and more than 10,000 alumni, colleagues, parents and other friends around the world.
