"Retirement will obviously involve all those books I haven't had time to read, and my husband and I are also embarking on a new adventure in a different city.
"We have a house and two acres waiting to be 'done up'. I'm sure the future includes more time with family and friends, more opportunities to ride our e-bikes and to take up petanque again.
"They do say that in retirement you are busier than ever – I can definitely see that happening."
Gilbert's library career started in Rotorua when she was just 17, filling a junior role for two years.
In 1989 Jane returned to Rotorua Library as a lending services librarian, then successfully applied for the director position she has been in for 24 years.
Gilbert was made an associate member of LIANZA (Library and Information Association of New Zealand Aotearoa) in 2004.
She said one of her career highlights was the opening of the new Rotorua Library within Te Aka Mauri in 2018, a unique partnership with the Lakes District Health Board.
This was "exciting, amazing and very satisfying" for Gilbert.
"I'm so proud of how the staff handled the pressure, how well they performed and how everything came together. Even while we worked through the expected teething issues, the staff remained positive and the end result is a library like no other."
She said the library was on track to make a big difference for its users.
"No longer do we refer to 'how it's been done in the past' but we really consider what the community wants and how best to achieve it."
Te Aka Mauri has received numerous awards and accolades since it opened, including the award for collaborative government action at the Local Government Excellence Awards on April 11.
Rotorua Lakes Council manager of arts and culture Stewart Brown said Gilbert had provided an invaluable contribution to the organisation.
"The Rotorua Library has grown and developed in unique and innovative ways under the strong leadership of Jane for more than a quarter of a century. Her knowledge and connections, both in the library industry and local community, will be greatly missed.
