That's not bookbinding, it's a cheap not-quite-replacement for the real thing. When difficult-to-replace volumes from your personal library start losing pages you see a bookbinder, not your corner photocopying business. University libraries used to have them on the staff, but they seem to have gone the way of the glassblower in the chemistry department. I understand that one can find still find bookbinding shops in strict-orthodox communities, people like to keep their prayer book, even after the original binding has given up.
