OpenURL is a web standard that makes it easier to link between different websites and other sources on the internet. OpenURL helps you find information and resources that are related to each other. For example, if you read a book review online and it mentions the author, OpenURL would let you click a link that takes you to the book's page so you can find out more about it. OpenURL works by sending information about the source you're looking at (such as an article or book) to different websites for information about that source. These websites can then send you links or information that is related to the source you're looking at. It's like asking a bunch of different websites for information about the same topic, so that you can get the best results.
