Historic Photograph Collection at Vancouver Public Library
In looking at Vancouver Public Library's website, I suddenly realized they offer a database of historical photographs digitized and otherwise indexed via their Special Collections section of their website. Just to give you an idea of the collection size, this is what they write:
"The Historical Photographs Subject Index provides access to the entire collection of over 87,000 accessioned photographs." Wow! Here's the link if you want to do a search as they do not appear to be part of Images Canada at this point.
