That's still an important skill! You might think that everything that can be digitized has been and is easily available online, but that's not the case. Especially so for more obscure books and publications that are mostly relevant to your local area.

When I moved to my current town and visited their library, I very quickly found some books written about the local area for which not much info existed online. It's a great way to spend some time if you're into that kind of thing!
