The Forsyth County Public Library Friends & Advocates had its largest semiannual sale over the weekend, raising more than $7,000 for library programming.The money, in combination with spring sale donations, will be used to fund summer reading programs in 2011, spokeswoman Paula Glover said.Glover estimated that about three-fourths of the more than 10,000 items available were gone after the three-day sale, which began Friday for members and opened to the public Saturday and Sunday.More than $3,000 was raised from members, some of whom she said joined at the door to gain first access.A new section of antique and autographed books was a “big success,” Glover said.Among the sales was a set of “National Geographic” magazines from 1914 to 2006.Some of the books remaining after the sale were given to charity, but many will be saved for the spring sale.“There was just too much to sell in three days,” Glover said. “Our spring sale, even if we got no other donations, would still be awesome.”Donations haven’t been a problem for the Friends, though. Glover said the high volume has led the organization to consider holding more than two sales per year.
