Origin and Publishing Roots

The brand origin of the Department Q series is Denmark, where Adler-Olsen first introduced these characters and narratives. However, the physical edition shown in the image is a product of the Spanish publishing landscape. Debolsillo was originally founded in Spain in 1957 by Janés Editores and has since become a cornerstone brand for pocket-sized literary works. This edition is printed and distributed primarily in Spain and Latin America to serve the Spanish-speaking demographic.

Ownership and Global Presence

Debolsillo is currently owned by Penguin Random House Grupo Editorial, which is a subsidiary of the global publishing giant Penguin Random House. On a larger corporate scale, the ultimate ownership lies with Bertelsmann, a German multinational conglomerate headquartered in Gütersloh. As of 2026 and historical trends, Bertelsmann remains the sole owner of Penguin Random House, making it one of the largest and most influential media and education companies in the world.
