Another milestone event in the Ottawa is the annual Friends of Library and Archives Canada Used Book Sale. A small group of volunteers work year-round collecting and sorting donated books. Along the way they find many books of special interest, some special enough to add to the LAC collection, some that are diverted to special causes. This year the venue is again the St Laurent Shopping Centre, and the dates 17, 18 and 19 September. The best books go early so is it's best to be there for the opening at 9:30am on Friday.
