Hello, I'm El cid, el campeador. I noticed that you made a change to an article, Charles Babbage, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. ‡ Єl Cid of ᐺalencia ᐐT₳LKᐬ  16:39, 26 February 2018 (UTC)
