Just found this blog. Have no idea who created and manages it, but wonder if you accept additions and how you want that information sent? Jim.
Thanks Jim. Yes, I have added contributions outside of my own collection in the past. Using the email address found in the profile, (bottom of page) send a good scan of the face of your card and the reverse unless it is blank. Include any information you have about the date and place of origin of the cabinet card. I will research the photographer and add a page to the index. Thanks again.
