The city’s mobile library, Te Pahi Pukapuka, is celebrating its 75th anniversary at the WildDunedin NatureDome at Forsyth Barr Stadium on Sunday.
Weekly user Anne Dunckley, who is also turning 75 this year, said the book bus had been a part of her life since she was a child.
She remembered the rush of excitement she felt when she visited the bus in Pine Hill with her mother when she was a little girl.
Growing up, the bus helped develop her fascination and love for books.
She ended up becoming a librarian, gaining work experience at Mosgiel Library before taking on a fulltime role at the Dunedin Public Library.
Mobile library team leader Helena Bailey, who also drives the bus to its various stops, said the bus offered a relaxed atmosphere that was "very customer focused".

People came in and had chats and made connections with each other.
"It’s like they’re coming into a coffee shop, without the coffee.
"The books are really important, but it is also just having a community space that they feel welcome and comfortable in."
In Dunedin, it was harder to get to libraries because of the hills, so the mobile services had been a success.
The most issued books were children's books and the bus’s clientele was mostly retired people and young families.
The bus had about 2000 books, including magazines, adult fiction and non-fiction.
