More than 50 young people were thanked by the Deputy Lord Mayor for their hard work spending the summer holidays helping library staff.
They all volunteered to help children with their reading and assisted staff to run activities as part of the Summer Reading Challenge.
The Summer Reading Challenge sees young people reading at least six books to collect stickers and get other treats.
At a special celebration event the volunteers were presented with certificates.
Cllr Kevin Maton, Cabinet Member for Education and Skills, said: “It is so impressive that more than 50 of our young people chose to spend a big part of their summer holidays helping others.
“I know the children who took on the Summer Reading Challenge loved having young volunteers helping them and this opportunity has given our young people an opportunity to develop valuable skills including teamwork and communication. Our library staff have had nothing but praise for them.”
