In a blog that the Calgary Public Library has called the Community Heritage and Family History Blog, there are posts on The Story of the Big Ditch, City Hall Celebrates its 100th Anniversary, What's in a name?, Calgary, Alberta in 1962, and Islands in the Stream - Heritage Roundtable to name a few.
While you are there you can also go to Calgary Public Library’s Community Heritage and Family History Digital Library.
At their site, they have the Alison Jackson Photography Collection, Postcards from the Past, and the Judith Umbach Photography Collection.
