1. Books are still one of the primary uses of libraries. It's just that they no longer are their only use. 2. Why do we call our smartphones phones at all? I mean, sure, they can make phone calls. But most people use them mostly for things that are not phone calls or phone-related at all. That's how language works. Look at the etymology of any word you like. More likely than not, the literal meaning refers to something historical that may or may not apply or exist anymore. For example, software developers are called engineers. Does that mean they are experts when it comes to engines? And not just software. Civil engineers don't know much about engines either. Yet for hundreds of years, they have been called engineers and for thousands to come, they will be. This is not a bug. This is the natural life of words in human languages.
