How we scored them
The Shelf Score weighs fit, contents and edition, value, and listed reading age or level. Four of the five picks state a reading age, and three state a grade level too; the title-only pick states neither. How we pick explains the weights.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| Chasing Space by Melvin | 9.8 | 32 | 22 | 21 | 9 |
| Who Was Sally Ride? by Stine | 9.7 | 30 | 21 | 21 | 9 |
| Buzz Aldrin by Jazynka | 9.7 | 30 | 20 | 20 | 9 |
| Counting on Katherine by Becker | 9.7 | 30 | 20 | 20 | 7 |
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.
