A thin notebook to record information and impressions of books you have read.  It is one size smaller than a paperback book, so you can carry it in a book cover with the book.  You can record the reading of 20 books in one notebook. Circle each book on the reading chart to see what kind of content it contained. The chart format is easy to review at a glance.  You can write down your impressions of the book and the synopsis of the book, such as one word you found in the story that resonated with you and when you would like to remember it. You can also write a summary of the book.

40 pages for 20 books
The book is in Japanese
