Discover brings you a shelf. This brings you whatever you ask for. It opens on what you asked before. Start with the question, in your own words. Narrow it by topic if that helps, or leave it at any topic. Then where to look. Research papers, YouTube, podcasts, news and blogs, or the general web. Then how recent it should be, and how many you want back. A search costs one of a monthly allowance, and the form tells you how many are left before you spend one. Then it goes and looks. What comes back is a list of candidates, each one a real piece with a real source. Keep one and it starts preparing. Added to your Library, like anything else you saved. A question, and something new on your shelf because of it.
