Well practically speaking you could just use images and then have the first book as a sort of pictionary with words and pictures that demonstrate them. Once they figure out enough words they can start to figure out other words that can't easily be explained by a single picture, and grammar can be worked out from there. Sort of like the Rosetta stone.

But this is useless to the post-apocalyptic hunter gatherer, civilization would have to be reestablished by then. And hopefully they at least understand the idea of writing words on paper and don't just worship it as a religious thing.

There has actually been work on doing that, attempting to mark radioactive waste dumps in a way even someone in a completely different culture from a distant future could understand. It's really interesting and there is pdf on it here: http://prod.sandia.gov/techlib/access-control.cgi/1992/92138...

If you are going to communicate with a completely alien civilization, that is one that can't even understand images, expressing information is even more difficult. My best guess is that you send a message with a really obvious pattern to it, then use that pattern as a basis for sending more information.

For example, send a ton of examples of simple code in a simple programming language, and their output. They can figure out what it means. Then encode your messages in the programming language somehow. Send a simulation of 3 dimensional space and little objects in it interacting, for example.

A movie might work.

It could possibly be made future-proof by using a flipbook format, assuming we can find a suitably long-lived material to print on.

An animation of what? It would be much more difficult and take way more space for a flip book, and it doesn't contain much more information than a few pictures, let alone a book full of pictures.
I was thinking an actual film, which wouldn't be difficult.

I kept thinking about the "how to tell future people about radioactivity" example and I think it's hard to convey the actual effects, while it may be easy enough to convey that it's dangerous.

A movie would be much more apt at explaining what was there and what the consequences of irradiation are that a few stills.
