OldSF在线旧金山历史网简介：
旧金山历史(Old San Francisco Historical)是一个公益性的老照片图集站点，采用地图+图集的模式来介绍美国旧金山的历史，网站采用了一种名为SFPL的模式来开发的，可以帮助我们了解美国旧金山城市的历史。
登录网站后会你会看到一副旧金山城市的地图，凡是有黑点的部分都是有图片的，点击黑点就可以在右侧展出来相对应的图片，所有的这些图片都是来自于旧金山公共图书馆的历史照片集。
This site provides an alternative way of browsing the SFPL's incredible San Francisco Historical Photograph Collection. Its goal is to help you discover the history behind the places you see every day.
And, if you're lucky, maybe you'll even discover something about San Francisco's rich past that you never knew before!
Where did these images come from?
The images all come from the San Francisco Public Library's San Francisco Historical Photograph Collection. They were culled from many sources, including the now-defunct San Francisco News-Call Bulletin.
The Library retains the copyright for many of these images. For details, please read their Permissions page and FAQ.
The creators of this site did not collect or digitize any of these images — credit for that massive undertaking belongs entirely to the Library.
