Are you old enough to remember when, if you wanted to know something, you had to spend an afternoon at the library, and that was often just a starting point to a long journey?
Today, just YouTube or Google it, and those too young to remember don't appreciate what they have.
Until recently, you could buy these obsolete pieces of furniture for a song. Now you will pay about a grand for one in reasonable condition. They're now pricy classics.
