I think you're overstating the importance of that role. The importance of libraries is that they employ a consultant that can tell you the name of a book that has the information you're looking for? And this performs better than reading the blog or publication of a field specialist? Even Wikipedia does a better job at this than any librarian I've ever talked to at any library. The most I've seen one do in recent years is enter my question into a computer and tell me the products available like an autozone employee. Nobody just has the depth of knowledge you imagine in their head at all times at a library.
