Old Book Fair: Thirty-Seven Bookstores and a Tribute to Calleja

Published on April 30, 2026 | Translated from Spanish

Madrid inaugurates this Thursday the 48th Antiquarian and Second-hand Book Fair on Paseo de Recoletos, with a prologue by Julia Navarro. Until May 17, 37 specialized bookstores from all over Spain turn the promenade into the country's largest backlist bookstore. This edition pays homage to the 150th anniversary of Editorial Calleja, a benchmark in children's and school literature.

How to manage the stock of 37 bookstores without losing your mind 📦

The logistical coordination of the fair requires a centralized inventory system to avoid duplication among exhibitors. Each bookstore uses its own databases, but they are unified into a common catalog with ISBN codes and condition status. Temperature and humidity control is critical for antique copies; IoT sensors and tents with climate control are used. The official app allows geolocating stalls and checking availability in real time.

The book nobody read but everyone wants to own 📖

Of course, the most sought-after item is not a Calleja manuscript, but that 80s copy with a scratched cover worth 200 euros. Booksellers know this and place it on a lectern with its own lighting, as if it were the Holy Grail. Meanwhile, tourists take selfies with books they don't intend to buy. The fair is a museum with prices: you touch, you smell, but if you open your wallet, it hurts.
