The event is organised by the Rotary Club of Dubbo Macquarie and will be held on May 1 and 2.

The first book collection will take place on January 28.

Book fair coordinator Peter English says there is excitement around this years event.

"A lot of people missed coming along to the book fair last year," Mr English said.

"We've been fielding inquiries for months now from people wanting to know how to drop off their books and whether the book fair would be back this year."

Those who would like to donate books can leave them out the front of Meals on Wheels at Mountbatten Drive Dubbo between 9am and 5pm on January 28.

The drop off will be contact free and COVID safe with designated pallets and clear signage indicating where the books should be left.

Mr English feels this years event may be one of the biggest in the state.

"We already have over 10,000 books stored and ready for this year's book fair but we are still looking for more," Mr English said.

"Our book fair is one the biggest and cheapest in the whole state."

The Rotary Club will extended their risk management plan for this years event to include a COVID-19 safe implementation plan.

"The public is now used to complying with QR check in codes, collection of personal data, use of face masks where required, sanitiser stations and following the directions of COVID safe marshals," Mr English said.

"We'll be following all necessary directions as required by NSW Health and the local council."
