On the map above, a user can hover over any state and see the Image and Indexing status for that state. Just below the map is the search fields for State, county and city/township or ED description. I knew the ED number for my Carringer family (62-63A). I input California, San Diego, and San Diego into the search field and saw:
This page told me that there were 208 EDs for the search terms. Way down the page is ED 62-63A:
The order of these listings is unclear - it seems random to me. If I did not know the ED number, I would be totally lost. There are no links available to ED maps (that I saw...). It would be a lot easier for users who know an ED number if the list was ordered by ED number.
Actually, there's an easy way to go directly to a specific ED number - the user can put the ED number in the "City/Township or Enumeration district" field on the search engine on the home page. I went back and put State = "california" and City = "62-63A" and it easily selected the right ED:
Clicking on that link for ED 62-63A opened the first image of the 40 page images in the ED:
The user can use the controls on the menu line above the image (Full Screen, Zoom in, Zoom out, Rotate, Invert) to manipulate the image. The image number is above the "Full Screen" menu item. A user can go to a specific image number by editing the entry in the Page field. On the top line (the one with the ED description) has advance arrows to move to the previous or next image on the far right next to the Search link.
The user can move the page image around using the mouse drag function (I call it "the magic hand").
I zoomed in a bit, then advanced to Page 2 (it took about 40 seconds) and was surprised that it took so long. It took over 40 seconds for every page change on my computer. I finally got to Page 34 of 40 and found my Carringer family. It took over 30 minutes to do this. Here is the page:
