I’ve shared items from Library and Archives Canada and many from the City of Ottawa Archives. I’ve recently discovered that the Glebe Report, the community newspaper, has put their archives online at http://www.glebereport.ca/Newspaper/Archives.php.
The archive is not searchable or indexed, but the PDF files high-quality and are easily browsable. Every issue I looked at has something of interest from the ongoing debate over Lansdowne Park to the controversy over enclosing the Fifth Ave. Court. It turns out that renovating/closing/reviewing Glebe area schools has been going on a long time.
This is a fanstastic resource for local history and heritage.
The school news sections are great, trying to imagine what the grade six students with their science projects are up to 30+ years later. I have copied some examples below.
