Why, Old SF, of course! It’s an awesome site that allows you to see old photographs of San Francisco from the location where they were taken. It’s an amazing tool for taking really interesting information (old photos) and putting them in a context that makes sense (your mental map of what the location looks like today).
It’s an incredible labor of love, built entirely as a volunteer project byÂ @danvdkÂ and designed byÂ @ravejk. They took a huge portion of images from the San Francisco Public Library historical image collectionÂ and geocoded them so that they could be displayed on a google map. How many images did they geo-code? About 13,000, which is more than half of the images with an identifiable location.
I spent some time on the site over the weekend, and it is amazing how much time I spent looking at old photos of San Francisco. People always ask me about the history of the home they are buying, and this site offers an amazing way to check out a neighborhood without having to spend hours digging through files at the public library.
Take a moment (or two, or three) and check it out. I think you’ll be as amazed as I am. If you are technically inclined, there are some ways that you can help keep the site developing. Â What other historical resources and websites do you really like for learning about the history of a San Francisco home or neighborhood?
