Authors are gathering at a south London library to protest at plans which could see it closed to save money.
Edmund De Waal, Sarah Waters and Stella Duffy were among those taking part in the protest at at Minet Library, in Lambeth, on Saturday afternoon.
Campaigners said former prime minister John Major used Minet Library to do his homework.
A Lambeth Council press officer said no final decision on library closures had been made.
"We have to make £79m worth of cuts which includes £37m just for this financial year," he added.
He said Minet Library was one of four libraries in the area with the highest running costs but a public consultation would start in April before any decision was made.
"No closures are proposed for this year and we are exploring the possibility of residents taking over the running of some libraries," he added.
Vauxhall MP Kate Hoey said: "The Minet Library is more than a library, it is the centre of the community it serves. It would be unthinkable that in one of the most deprived parts of Lambeth it could close."
The Knatchbull Road library is hosting readings from each author and the world-travelling The Itinerant Poetry Library was also visiting.
