City of Edmonton Archives have put 25,000 historic photos online for all to access and the good news is that there are more to come. If you find a photograph of particular interest to you a high quality copy can be ordered from the archives.

I understand that this project is just the start, documents held at the archives will be added to the web site in due course.
