Your post was well written and easy to read. I can tell you have put a bit of thought into it. I too am frustrated by people saying Google knows all the answers. If you want a quick easy answer for a quick easy question, Google has its merits. However, if you actually want an understanding of the topic then you do need a librarian.
It’s interesting how you mentioned blackouts in rural areas. Without power they are unable to use the internet so they have to resort to books. Last semester as I was researching for an assignment, I read there are many students who don’t know how to use an encyclopedia. In one extreme case there was a high school student who routinely used his Grandmother’s encyclopedia from 1911, he apparently didn’t see why he shouldn’t be using it. It is a fascinating insight into the divide between the city and country.
