As a nonfiction writer, I have a lot of opinions about sourcing. Not whether it needs to be done but where it should be included in the work. Right now, I’m reading Eve: How the Female Body Drove 200 Million Years of Human Evolution by Cat Bohannon. The back matter comprises an index, a full (and impressive) bibliography, and notes. There are also in-text * to denote explanatory notes at the bottom of individual pages. These notes are conversational in nature and add to what’s being said in the text. I like the use of explanatory notes that don’t read like a mini-thesis; these bring needed information without breaking the voice.
What do you think? How do you arrange your citing, sources, and explanations in your work?
