- URI: Uniform Resource Identifier
  - URL: Uniform Resource Locator
  - URN: Uniform Resource Name

A book example ("Leadership in Turbulent Times" by Doris Kearns Goodwin).

- `urn:isbn:978-1476795928` - Uniquely identifies by "name"
- `https://www.barnesandnoble.com/w/leadership-doris-kearns-goodwin/1128008541?ean=9781476795928#/` - URL, "L" is for "Location"; tells you were something is "at"

Both are "URIs" one is a URN and the other is a URL.
