How we scored them
The Shelf Score weighs fit for a teen reader, contents and edition, value, and the listed reading age or grade level where one is given. How we pick explains the weights.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| Animal Encyclopedia by Spelman | 9.6 | 30 | 21 | 20 | 4 |
| Encyclopedia of Animals by Cooke | 9.6 | 30 | 22 | 20 | 0 |
| Zoology by DK | 9.5 | 28 | 20 | 19 | 0 |
| Animals by Wonder House | 9.4 | 23 | 16 | 18 | 5 |
| Picturepedia by DK | 9.4 | 21 | 19 | 18 | 4 |
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.
