Done Thaumcraft research note questions.

So, I'm super new to Thaumcraft as I just started it, I was running around the world scanning everything possible including nodes, and I started to unlock research in my book, but as I was unlocking it I didn't have a pen and paper in my inventory to make the research note for it, how do I make the research note after the fact ?

 

If you are totally new to Thaumcraft, a video such as this: could be very useful to you.

 

I watched some of those videos but they didn't answer the above question, Thumcraft on Infinity appears not to need research notes like previous versions, so I've figured it out but thank you for your response.
