#book care

I've been thinking about this a lot lately, maybe it's because I've been working on a new beer recipe and I had to annotate a bunch of notes 😊. But anyway, I was wondering what you guys think about writing in the margins of books. I mean, some people swear by it, like it helps them engage with the material more, while others think it's sacrilegious. I've done it before, but only with books I don't plan on selling or passing down. What about you? Do you annotate your books or keep them pristine? 🤔
