The third Saturday of this month is the Deschutes Public Library's Spring Book Sale. All the usual details apply; it's taking place at the Library Administration Building basement at 507 NW Wall Street downtown. Date is Saturday, April 19th, time is from 10am until 4pm. Get there early for the best selections; I believe hardbacks and large-formats are $1, paperbacks are 50 cents, and kids books are $1 per inch (stacked), but don't quote me on that.
