I've just returned from a fabulous 3-day Teacher Institute at the Library of Congress. The Institute brought together 20 teachers and librarians from all over the country, and we explored using primary resources. We learned ways to incorporate them in our lessons, which was great, but the best part was meeting staff members from the LOC and going into the different reading rooms. I got a readers' card so I can go back any time and go into the reading rooms.
We used the tunnels underneath the buildings to get from one to the other (I didn't even know that there were three buildings!) and went on a fabulous tour of the Jefferson Building. My favorite place, though, was the Adams Building, which is a beautiful art deco style building. Here's a picture of a lamp on the side of the building.
We met the head of the Science & Business library, and she is a 51-year employee dynamo! What a cool person! Her area of expertise is household technology, and she was so excited to show us a neat collection of irons and other household items from the past.
