How we scored them

The Shelf Score weighs performance, build, value, safety and warranty. For books, performance means fit to the list’s topic: biographies under 400 pages score highest, and books over the bar score lower. No warranties apply to books. How we pick explains the weights.

Book Shelf Score Fit /35 Contents /25 Value /25 Age/level /10
Intimate Audrey 9.7 33 21 20 n/a
Carson the Magnificent 9.7 32 20 20 n/a
Out of the Shadows 9.7 30 20 20 n/a
Lucky: A True Story 9.6 30 20 19 n/a
Titan: The Life of Rockefeller 9.6 23 22 19 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.
