For a really long term, a cooperation with some brickworks, where a brick printer would be introductd in the brick producing process, so that Wikipedia (and other important works) would be printed on every brick produced. We know that Sumerian tablets have lasted for thousands of years, so these bricks would surely last that long too.
And for even longer, do the same with bottle manufacturers.

This method of making a lasting impression on concrete is said to be not much more expensive than ordinary concrete.
