Berlin Wall's fall, in original documents

Good that the Wall came down, and cool that we can read some of the original documents from that time shedding light on what happened:

A letter to Mikhail Gorbachev from an adviser, who said the wall has come down and socialist system is finished.

Documents about East Germans fleeing to the west through Czechoslovakia.

 Once-secret documents show opposition to German reunification by U.S., others.

The CIA's "Outlook for Eastern Europe in 1990."  Put "Berlin Wall" in the search bar.
