In 2008, Jones published Washington Irving: An American Original, a project he spent seven years writing and researching. As one of the first biographies of the American author and statesman in eight decades, Washington Irving was praised by the Associated Press as "authoritative" and "charming" by the New York Times. In 2010, Jones was awarded the Washington Irving Medal for Literary Excellence from the St. Nicholas Society of New York. Jones has been an active member of Biographers International Organization, a non-profit organization founded to promote the art and craft of biography, since its inception in 2009. In 2012, he was elected vice president of the organization, and in 2014, he was elected to a two-year term as BIO's president. In September 2013, Jones published Jim Henson: The Biography, the first comprehensive biography of Muppet creator Jim Henson. Hailed as "masterful" by Kirkus Reviews, Jim Henson was a New York Times bestseller, and received the 2013 Goodreads Choice Award for Best History & Biography, as well as being selected by CNN viewers as a "Favorite Book of 2013.". Henson's longtime associate Frank Oz publicly praised the book, saying, "Brian Jay Jones has captured the layers of Jim’s genius and humanity, as well as the flaws that made Jim, like all of us, so delightfully imperfect. Jim needed this book to be written," while lifelong Muppet fan Neil Patrick Harris called it "an absolute must-read!" Named a "Book of the Year" by Bookpage, it was also shortlisted for the Plutarch Award for the best biography of 2013. December 2016 saw the publication of George Lucas: A Life, a full-length, comprehensive biography of Star Wars creator George Lucas. Lauded by the Washington Post as "admirably comprehensive", George Lucas was hailed by Kirkus as a "sweeping, perceptive biography," and was named one of the Best Books of 2016. In May 2019, Dutton published Jones' biography of children's author Dr. Seuss, Becoming Dr. Seuss: Theodor Geisel and the Making of an American Imagination. The book was praised by NPR as "nuanced, profoundly human, and painstakingly researched," and received positive notices in the New York Times, The Wall Street Journal, and Washington Post. A self-proclaimed "pop culture junkie," Jones has discussed at length his particular affection for the Beatles and comic books, especially the character Batman and the writer Alan Moore.
