J.D. Salinger's works remain as popular as ever. Today

The airing of a J.D. Salinger documentary has returned "The Catcher In the Rye" to the top of bestseller lists.

"Catcher" was No. 1 on Amazon.com and No. 20 on Barnes & Noble.com within hours of "Salinger" appearing Tuesday night on PBS stations.

Rankings for other Salinger books also surged. "Nine Stories" was No. 77 on Wednesday morning, jumping from No. 6,639 the day before. "Franny and Zooey" rose from 6,191 to 172.

The documentary directed by Shane Salerno was released in movie theaters last fall. It alleges that at least five new books by Salinger will be published.

Salinger reportedly wrote steadily over the last 45 years of his life but permitted nothing to be released. He died in 2010 at age 91.
