The fall Friends of the Library book sale is this weekend at Arlington Central Library.

"It's quite a scene," library spokesman Peter Golkin said. "It's kind of like a rock concert."

The Friends of the Library hold two "mammoth" book sales each year — one in the spring, one in the fall. Smaller sales are held throughout the year at other branches.

The event kicks off at 5:30 p.m. Thursday. Thursday night is members-only, though you can pay the $10 membership fee at the door, Golkin said.

Book enthusiasts begin lining up for the Thursday kickoff several hours before doors open, he said.

The sale lasts through the weekend, with Sunday being half-price day.

The sale is held on the first level of the Arlington Central Library parking garage.
