How we scored them

The Shelf Score weighs fit for the curious reader, contents and edition, value, and the listed reading age or level where one is given. Two of the five listings give a reading age and grade level; three give neither. How we pick explains the weights.

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.

How to choose the best nonfiction books for general knowledge

Match the book to the reader

The DK encyclopedias suit curious kids with CGI visuals at grade 4 to 7, while the 704-page Book of Extraordinary Facts suits an adult trivia lover. The bathroom trivia book is billed for all ages in short bites. For group reads, see our book club books.

Encyclopedia or trivia collection

Encyclopedias organize knowledge by topic with visuals; trivia collections deliver bite-size facts. The 1572-fact book splits into 63 chapters of 25 factoids for dipping in and out, while the DK titles build topic by topic.

Check the edition and the fine print

DK History is the illustrated edition from 2019, and its listing gives a reading age of 8+. Note the contradiction on the DK Human Body listing: reading age 4+ against “perfect for ages 9-12”. For younger readers, see nonfiction books for kids.

Before you buy

• Check the format: the Book of Extraordinary Facts is a 704-page hardcover, the others are smaller paperbacks.
• Match the listed grade level to the reader, and read the description for the topic mix.
• For the DK titles, confirm the edition year so a classroom set matches.
