KNOXVILLE (WVLT) -- Reading is fundamental, but it also costs a lot of money to keep literacy based education going.
That is why for more than two decades, Knox County's "Friends of the Library" has made it their mission to keep reading programs funded in their library system
To do so, they raise money by holding an annual used book sale.
On Sunday, it kicked off by allowing only members to shop their racks inside the old Knoxville Convention Center.
On Monday, the doors will open to the general public, offering thousands of titles ranging in price from $0.50 to $2.
"Our libraries are very badly under-funded, so this is an opportunity for us," said Jena Mashburn, from the Friends of the Library. "We don't do materials purchases, but we do special programs and special needs."
Last year's book sale raised about $50,000.
Organizers hope to raise even more this year.
