Hello, I'm John of Reading. An edit that you recently made to Help:ISBN seemed to be a test and has been removed. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! John of Reading (talk) 12:05, 5 April 2019 (UTC)
