The nominations list, unlike others with YALSA, is simply that: a list of exceptional YA books. Throughout the year, YALSA awards several honors to young adult authors. The Morris Award, for example, annually honors a debut novel by a YA author. The most longstanding YALSA Award is the Edwards Award, which began in 1988 and is given every year to a young adult author for his or her longstanding effort in the genre. The most recent honor, the YALSA Award for Excellence in Nonfiction for Young Adults, only began last year.
