Costa Book Awards
The Costa Book Awards are a set of annual literary awards recognising English-language books by writers based in Britain and Ireland. They were inaugurated for 1971 publications and known as the Whitbread Book Awards until 2006 when Costa Coffee, a subsidiary of Whitbread, took over sponsorship. The companion Costa Short Story Award was established in 2012.
The awards are given both for high literary merit but also for works that are enjoyable reading and whose aim is to convey the enjoyment of reading to the widest possible audience. As such, they are a more populist literary prize than the Booker Prize.
In 1989, controversy erupted when the judges first awarded the Best Novel prize to Alexander Stuart's The War Zone, then withdrew the prize prior to the ceremony amid acrimony among the judges, ultimately awarding it to Lindsay Clarke's The Chymical Wedding.
Process
Authors need not be British or Irish but they must have been resident in the UK or Ireland for at least six months in each of the previous three years.
