How we scored them
The Shelf Score weighs fit for the reader, contents and edition, value, and the listed reading age or level where one is given; none of the five picks lists one. How we pick explains the weights.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| Three Critiques by Kant | 9.8 | 32 | 22 | 21 | n/a |
| Meditations by Aurelius | 9.6 | 28 | 20 | 20 | n/a |
| The Kybalion by Three Initiates | 9.5 | 27 | 18 | 18 | n/a |
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.
