Even so, Dylan did still gain a book award, for the first part of his autobiography (published in 2004), ‘CHRONICLES Volume One’. See AOL News (12 October 2005):
‘Rowling, Dylan win Quills prizes for books’. Extracts:
‘J.K. Rowling led the list of writers winning prizes at the first Quill Book Awards on Tuesday, and singer/songwriter Bob Dylan was awarded the biography/memoir prize.
The winners were determined by online consumer voting from a list of nominees put forward by a national panel of 6,000 librarians and booksellers.
Rowling won the prize for book of the year and best children’s book for "Harry Potter and the Half-Blood Prince" while Dylan won best biograpy/memoir for "Chronicles: Volume One," his personal history as a musician and tortured pop icon.
Neither author was on hand to accept their award. But Rowling, who said her travel was limited because she needed to look after her young child, gave a video-taped acceptance.
The Quills mark a challenge to the more staid National Book Awards and the Pulitzer prize, which have tended toward works with strong literary merit but little public recognition.
