New working lists of US Federal and State GIS portals

Joseph Elfelt of MappingSupport.com has compiled a very helpful working list of addresses for over 40 federal ArcGIS servers with open MapServer and ImageServer data:

And a list of over 50 state server addresses:

The lists also contain some key caveats and tips for finding local GIS data as well.  Joseph is open to the community contacting him with additional federal or state servers to add them; his contact information is at the top of the lists.  That these already excellent resources will continue to be updated is very good news.

    Update, April 2018: Joseph Elfelt has updated the above information with the following:
    His work has now been combined into a single pdf file. In addition, internet addresses for various regional, county and city ArcGIS servers have been added. As described in the following pdf file, these 600+ GIS server addresses were found with simple Google searches. Here is the updated list:
