They say that only a small part of a book is truly worth reading. This book is like a condensed catalog of the parts of Direct Publishing books that are worth reading. Just flipping through this book will give you an effect similar to actually reading many books. This book has considerable value and is a popular item on Mercari. It's the perfect book when you're stuck for ideas or looking for good ones. It's not for sale, but I obtained multiple copies, so I'm listing an unread one this time. I really recommend this book. Please get your hands on it.
