How much better it will be, then, to make cell phones and related tools work for the library, rather than making librarians rush around like the zealous shushers of yestercentury, trying to keep this new tool off of our turf. Let’s shift this conversation. Though I suspect we’ll be shushing our users for a long time to come, the conversation should not be about whether to outlaw cell phone devices but how best to put the library into and onto these phones. After all, banning the cell phone will one day seem as silly as trying to ban the laptop.
