Sure. And you can replace it with a compass and map, which doesn't take much room, if you only need a local map. I don't think an eBook reader is strictly analogous. It's much, much smaller than the library of books it contains would be in paper form. A paper library is fine for shelter-in-place or if you have a cabin to bug-out to, but not if you have to carry it. By all means have paper versions of crucial documents and reference works. Beyond that, it's either eBook or nothing for travel.

(Pack a deck of cards, too. In a medium-term survival situation, an eBook reader has significant value purely for entertainment, but a deck of cards is hard to beat.)
