I need help finding out what this type of journal/book is called. It’s driving me nuts!

I’ve been trying to figure out what this type of journal/book is called so I can find it online to order it, but everything I search isn’t what I’m looking for. It’s like a travel journal I guess? And inside the pages there’s a section that opens up. It folds out to more pages. It’s essentially the same type of book in Practical Magic. The spell book where Sally looks to find the spell to bring her husband back from the dead. I can see it in my head and don’t know if there’s a name for it or just something I would have to diy (which I really don’t want to do).
