Since 1980, the Los Angeles Times has awarded a set of annual book prizes.
In addition, the Robert Kirsch Award is presented annually to a living author with a substantial connection to the American West.
An award named for Seidenbaum was added a year after his death in 1990.
The author of each winning book and the Kirsch Award recipient receives a citation and $500.
The prizes are presented the day before the annual Los Angeles Times Festival of Books.
