No, they're illiterate.
In fact, they think that writing is a form of sorcerery (it's amazing to them that people can communicate such detailed ideas with just marks--it must be sorcerery!), and they shun it.
But that doesn't mean that the traveler who came to trade for their steel didn't bring with him some interesting bit of info from afar. Or that, as the Barbarian PCs lived their lives, that, sitting around the campfire, stories were not told. Or even that individuals of other races (Aesir, Hyperboreans, a traveler from the Border Kingdom, Aquilionans) couldn't find their way through the clan's territory at one time or another.
Ok I still fail to see how in a limited amount of time your PCs managed to hear stories from individuals from all around the world (if we accept that someone would add useless details like in what street the library is in their tales).
Anyway, RAW aside our DM asks us to roll a gather information, in order to study the new area, so we can use our knowledge (local) there. I think it makes more sense than both "you know everything" and "you know only one city" suggestions.
