Each time I wander over to the US Whitehouse.gov website, I see more additions or changes. The people of American can download an iPhone app! This is the closest to the Federal government that people have ever been and watching their government in action.
Here's a Snip tool shot of one of the webpages. They have the social medica covered: FaceBook, YouTube, Twitter, blogs, cellphone, etc.
There is a virtual tour of the Whitehouse if you haven't visited it or can't. Go here to increase your information and knowledge of how our government works. The one that I liked is the addition of the listing for Resources to take you into the more detailed aspects of the Federal government.
My all time favorite, The Thomas Library of Congress. Congressional people can say anything, in today's world of government, it is when they put words in writing that binds them to what they say. It is also a very good resource for historians in that there is proof of what someone wrote, in perpetuity or unless the server crashes where the data is stored. Then it would be going back to the 'old' days of going through a paper copy.
The Library of Congress has many aspects. As you go through it, you will find a lot more information than the Congressional record. The Library also keeps information about International Law, Collections that are acquired by the Library such as Performing Arts, Newspaper Archives, Films, Maps etc.
Another resource is The Supreme Court of the US. It is interesting to read the history of the US Supreme Court and all of it's changes over the years. The building itself is impressive and a short history is here. A rare look inside was done by CNN & is posted at YouTube.
The architect of our Capitol is impressive.
