Actually brick and mortar libraries are very important;
1. Most books are not on the internet.
2. Somebody with a keyboard can’t change a printed book.
3. There’s a certain sensualness to a book. Touch, smell and look that a screen doesn’t have. Perhaps that is why many people long for the old phone-books.
MUCH easier on the eyes as well - given decent reading illumination.
(smile) There's a Youtube channel with some math teacher who absolutely loves the smell and touch of a hard-copy book.
