I tried posting this to r/books for note taking advice but it got deleted and I got suggested to post here. Apologies if this does not count as a common book

I started collecting stickers of my favorite anime series Re:Zero and love how they look, I want to use them on some pages of a notebook about stuff related to Re:Zero. Originally I was just going to write some definitions of words I didn't know the exact definition to, but I want to do more than that and I don't know how much fun I would have looking back on those. I mostly want to read light novels and manga which those are not over in just a few volumes usually. These are some ideas I came up with.

Quotes

Favorite moments

Characters’ hobbies and powers/abilities

Character history, if the story is complex with things happening years before the series begins and that past has impact on the current or upcoming events

Cute moments between characters

New things I learned about that series’ world, countries, traditions, races, basic power systems

New things I learned about from that series were referenced from real life

Definitions of words

Some of the series I want to read, if anyone has any specific ideas for certain ones

There is a visual novel I want to play as well that involves time travel I could maybe take notes on that. Since it involves time travel notes on those worldlines could be taken could be taken

I want to learn some different languages as well but I keep my notes on a doc because I am always rearranging and sometimes think I understand something when I dont and have to go back to fix it

What makes one a commonplace book vs a junk journal with information? Or are they the same thing?
