Here’s your takeaway: When there’s no author, use the title. Put it in quotes if it’s a short work (article, webpage, poem). Italicize it if it’s a long work (book, film, website name). Add a page number if you have one. That’s the whole recipe.
If the source is a webpage with no page numbers, just the title in parentheses works. For example: (“Vegan Recipes”). Your reader can find it in your Works Cited list. You’ve basically said, “Go look here, but I gave you a hint.”
