More than 30,000 books are stacked and ready in the Civic Theatre for the Rotary Club of Invercargill's annual Queens Birthday weekend booksale.
The Invercargill teen parents unit is one of the causes set to benefit from the sale, which Rotary has run for 33 years.
Rotary president Alice Pottinger said the sale, which raises around $55,000 each year, started out in a garage opposite Countdown.
It had now grown to take up much of the backstage area of the Civic Theatre and had become the club's main fundraising event, Mrs Pottinger said.
The sale runs from 8am to 8pm on Friday, 9am to 5pm on Saturday and Sunday and 9am am to noon on Monday.
