I have a very basic one, as the many failed journals in my life have taught me to keep it super simple.

I've ruled 4 horizontal lines across a page in my 2022 Brain Dump Book, and headed it '2022 Bookshelf'. Then I turn the book sideways, write the title, author, number of pages and starting date on the day I begin reading it. When I'm done I write the date and a sentence or so summing up how I felt, and how many stars/5 I give it. I then draw a box around it so it kind of looks like a book, and each book I do in a different colour.

And that's it. 11 months in, I've only filled about 3 shelves on an A4 page, but I have recorded every book I've read this year. For me, that's a huge success.
