About 35,000 books will be on offer at the Invercargill Rotary Club's annual book sale and bargain hunters will be able to browse through the haul from Thursday.
Rotary Club of Invercargill president Neil Boniface said it was not the most books the sale had ever collected but the quality of the books were probably the best they had.
"Some of these books have probably never been read."
People talked about how the information revolution would mean less people were reading books but the popularity of the book sale showed otherwise, Boniface said.
Encyclopaedias, dictionaries and atlases did not sell well but fiction books continued to be popular, he said.
While fiction books were popular, it would be the children's book stock that would most likely run low come the final day on Sunday, he said.
The annual fundraiser had been running since 1980 but there will be a few changes this year.
The event starts on Thursday evening at the Civic Theatre, allowing book fanatics to have an extra day from previous years to scavenge the table tops for the next gem in their collection.
The extra day would allow those who work on the weekend to have the opportunity to come down to the event, Boniface said.
The line of people that queued for opening day should be a lot less than previous years, with the extra day to spread out the event, he said.
The other change was that there wouldn't be any plastic bags at this year's event and Boniface advised people to bring their own.
The majority of the funds collected during the book sale will be donated to the Cancer Society.
