A library book, first borrowed more than 150 years ago, has finally found its way back to its home in Kiama, New South Wales after being discovered hidden inside a bricked-up fireplace.

The Antiquities of Athens, published in 1858, was recently returned to Kiama Library after a family renovating their South Coast home found it inside a tea chest concealed within an old fireplace.

Kiama Library manager Michelle Hudson said the family had no idea how the book ended up there but wanted to ensure it was returned.

“The family has been in Kiama a long time and discovered this as part of unveiling the old fireplace in the house,” Hudson said.

“They don’t know where it came from, but it’s lovely that someone thought this would be special to the library, and it is.”

Despite spending decades hidden away, the book remains in good condition apart from some weather damage.

Inside are the library’s original ownership stamp, opening hours, borrowing rules and overdue fines.

Based on the old penalty of three pence per week, library staff estimate the book would have accumulated about $28,000 in overdue fees after adjusting for inflation.

“Maybe that’s why we can’t find out who hired the book and they’re keeping their identity quiet,” Hudson joked.

Fortunately for the mystery borrower, Kiama Library no longer charges overdue fines.

Rather than returning to circulation, the historic book will now become part of the library’s Local Studies collection, where it will be preserved and displayed as a piece of the community’s history.

“We have a place for keeping these little treasures in the library and making sure the community members know about our heritage and our culture, so it’s a lovely story,” Hudson said.

The family who returned the book will be acknowledged for helping preserve the rare item.

The book also offers a fascinating glimpse into library life in the late 19th century.

Borrowers who were intoxicated were banned from taking out books, while anyone behaving in a disorderly manner faced a fine of at least five shillings.

Loan limits were also strict, with readers generally allowed to borrow just one volume at a time, although larger households could qualify for extra books if six family members could prove they were able to read.

Hudson said libraries had long played an important role in the Kiama community.

“We have a long history of libraries in our local government area and the library has been moved around town a number of times,” she said.

“We have a lovely home now, but libraries have been an important place in our community for a long time.”

The book was originally borrowed when Kiama Library operated from the Kiama School of Arts building.

Today, the library is located on Railway Parade, where the returned volume will be carefully preserved for future generations.
