We seem to be on a primary document roll. In school we can make use of more than our old student record card collection. Many items are on view in the front display cases. Here is a slide show with old news clippings and another that has photos.
The picture above is a screen shot of my lower east side map from my google map "collection." It can be made fully functional but it overwhelms the column. I learned about mapchannels from digital urban. The free site also gives you the option to create a link to a full size version of a google map.
