Han Kang's historic Nobel Prize win in literature has sparked a remarkable boom in Korea's publishing industry. Within just six days, the author's books sold over a million copies, and the ripple effect has extended beyond her oeuvre, boosting the sales of other literary works as well.

According to YES24, the country's largest online bookstore, sales in the novel and poetry category — excluding Han's works — rose by 49.3 percent between Oct. 10 and 16, compared to the same period last year.

Readers purchasing the Nobel laureate's books were frequently seen adding other works to their carts. Among the most popular titles were Yang Gui-ja's "Contradictions," a 1998 coming-of-age novel that saw a staggering 421.1 percent increase in sales, and Juhea Kim's "Beasts of a Little Land," winner of this year's Yasnaya Polyana Literary Award for foreign literature.

Books mentioned and recommended by Han have also been flying off the shelves.

Astrid Lindgren's children's book "The Brothers Lionheart" — which Han named as one of her childhood favorites that helped her grapple with "questions about humans or life and death" during her phone interview with the Swedish Academy — experienced a 35-fold surge in demand.

Two titles the author recommended to her novelist father, Han Seung-won, saw dramatic spikes in popularity as well. Mary Oliver's essay collection "Long Life" skyrocketed by 6,800 percent, while Elizabeth Strout's Pulitzer Prize-winning novel "Olive Kitteridge" soared by 2,466.7 percent.

The works featured in Han's "Five Books of My Life," a list she shared in 2014, have similarly seen a resurgence of interest.

In fact, the combined sales of Lim Chul-woo's short story collection "Father's Land," Boris Pasternak's essay "Death of a Poet," Wolfgang Borchert's "Generation without Farewell," Fyodor Dostoevsky's "The Brothers Karamazov" and art historian Catherine Krahmer's biography of "Käthe Kollwitz" saw a 20-fold jump.

While Han's Nobel win has temporarily injected new life into Korea's publishing industry and boosted its low reading rates, the country's distribution network, dominated by large booksellers like YES24, Kyobo Book Centre and Aladin, has funneled most of the additional stock of Han's books to these major retailers.

As a result, local independent bookstores have been left largely out of the supply chain, with many struggling to secure copies to sell.

The Korea Federation of Bookstore Association issued a statement, Friday, indicating that small, independent booksellers have not received any of Han's works from the wholesale distributor operated by Kyobo Book Centre since her Nobel triumph.

"While Kyobo Book Centre branches profited from selling Han's books, local sellers were left waiting indefinitely for their stock. Even when the sales of her books surpassed one million copies by Thursday, not a single independent bookstore had received them from Kyobo," the statement read. "In the excitement of the publishing world's long-awaited success, Kyobo Book Centre has turned its back on local bookstores, driven by greed."
