We track monthly sales from a variety of sources and compare the highest sale price items to historic quarterly pricing to determine if there is a significant shift upward. The results are further analyzed to determine the book categories being impacted. Our current book category breakdown includes:
Art/Photography/Architecture
Business and Economics
Children’s and young adults
Education/Reference
Exploration
Military, World History and Government
Modern first editions
Nature
Poetry and Literary criticism
Religion & Theology
Romance
Science
Science fiction/Fantasy
Separately, we track activity by author to determine if there is a significant increased interest in books published for a particular author. These include the most sought after rare publications and are filtered to exclude special attributes such as signed/inscribed by author copies from our analysis. Our current author breakdown includes:
Alexandre Dumas
Charles Dickens
Emile Zola
Honore de Balzac
J.D. Salinger
J.K. Rowling
J.R. Tolkien
James Joyce
Jonathan Swift
Leo Tolstoy
Scott Fitzgerald
T.S. Eliot
Tennessee Williams
Victor Hugo
William Faulkner
Lastly, our category breakdown and author inclusions are
reevaluated yearly to adjust by adding or removing from our sampling based on market trends.
