NEW DELHI: Every Sunday morning, a one-of-a-kind colorful maze takes shape near Delhi Gate, where thousands of paperbacks and hardcovers rise in towers and spill on tarpaulin beds, setting the stage for generations of readers on hours-long treasure hunts. From popular romances to classics in English, Hindi and Urdu, to manga, children’s comics, philosophy, cookbooks and coffee-table art albums, the open-air Sunday book bazaar has been serving as a cultural institution for decades.
