How to Search for Images Online

Did you know that you can search for images in our collection online, simply by using a “copy negative number”?

What is a copy negative number?

Copy negative numbers are used to identify a photograph or a work of art in our collection. They usually start with a C-, a PA-, or an e number, such as:

  • C-041979
  • PA-005001
  • e002505688

Copy negative numbers are usually included along with the image in the photo credit in books, articles or online.

So what do you do if you have found a copy negative number, in a book or online, and would like to know if Library and Archives Canada holds this image? How do you get to the image’s description in our database?

It’s simple, just follow these tips:

You can search Archives Search by copy negative number; however, there is a trick to it…

  • C- and PA- numbers must have six digits after the hyphen in order for our database to recognize them.
  • Zeros should be added at the beginning of a shorter number to create a number with six digits. For example, if you see PA-5001 you need to enter PA-005001.
  • Copy negatives starting with an “e” do not follow the six-digit rule (they do not require a hyphen either).
  • Look under the heading entitled “Conditions of Access” for the copy negative number starting with C- or PA-, or under “Terms of Use” for e numbers.
  • You will need the copy negative number to order a photographic reproduction or a digital image of a work of art.
