Jonathan Ross will officially open Hampstead Garden Suburb’s Community Library on June 28.
The Hampstead Garden Suburb resident will cut the ribbon at the official opening in Hill Rise at 11.45am.
In June 2011 Barnet Council announced that it would be closing two of its libraries due to funding cuts.
One of those earmarked for closure was the Hampstead Garden Suburb Library.
However, following a 2,500 signature petition the Hampstead Garden Suburb residents’ association put in a successful bid to save it.
Within days of its official closure in April 2012 it re-opened, this time run by 45 volunteers.
Since the re-opening attendance at the toddlers singing group has doubled and a story time for children has been introduced.
There are now plans for an adult book club.
Mr Ross said: “A local library is particularly vital for children, people without cars and as part of a vibrant community.
“That’s why I want to open it officially to make more people aware this library is here for everyone to drop in.
“I hope lots of you will come along at 11.45 to back me up and that you will use the library to keep it open in future.”
