Tai-Danae Bradley is writing a small book called *Applied Category Theory* which she will put on her blog in a while. It's largely based on the Applied Category Theory 2018 workshop, and it looks very nice.

I'm writing this partially to remind myself to make sure to tell all of you about this book when it comes out!

Her blog has some great stuff! I really started to understand limits/colimits and universal properties after reading her pages on limits/colimits.

Great! I met her at ACT2018. I only discovered her blog after that. It's got the best introduction to the Yoneda Lemma - a 3-part series that starts with the important 'Yoneda philosophy' before getting into the mathematical details.

She also ran a Public Broadcasting Service show on YouTube called Infinite Series, which unfortunately did not go on forever.
