we have worked in great partnership with our city librarian michael lambert who is also working with us. you might seen behind me is a wall of 15 different curated historic photos. one of the things you may not know is in order for this to be accomplished, we had to clear out many of our old property files. we went through this intensive process to digitize over a million files. when we went through that process, we found many, many historic photos we thought was not only worth preserving but sharing and putting out to the public space. something that is important to our history, buildings that used to look a different way but are important of our fabric, it is important to share that with san franciscans to come, not to put the away in a box never to be seen. we worked with the library to make sure we cataloged and got those photos to them to be accessible. we're proud to announce we have over 92,000 photo images that are available at our san francisco public library in order for people to see our history and our shared buildings and resources. these photos here are just a small set
