I went 7 for 9. I used Google as my search engine, and it worked well. As I found the sites by the numbers...
1) Piece of cake. Trotsky speaking in English...
Difficulty: Easy - second hit.
Found using "Trotsky" with an "AVI" file format.
Site: http://www.gn.apc.org/ito/trotsky2.avi
2) 1915 suffrage poem...
Difficulty: Easy - first hit.
Found using a phrase search with "When all the women wanted it"...
Site: www.geocities.com/Paris/Bistro/8066/ADMsuffrage.html
3) Letter from George Washington...
Difficulty: Moderate - required a little hunting.
This one took a while because many sites paraphrase Washington. Eventually, I got to it on the second search page of a Google key phrase search for "certain forged letters" and Pickering.
Site: http://etext.lib.virginia.edu/etcbin/
From here, you will have to drill down a bit through the menus.
4)Willie Lynch and slave owning...
Difficulty: Easy - after a little hunting.
I used a key word search with "Willie Lynch" and slave.
Site: www.freemaninstitute.com/lynch.htm
5) Online debate over Cuban Missile Crisis...
Difficulty: Kicked my butt -- I never found an online debate.
I found several sites with views recorded about the Cuban Missile Crisis and the deterrent effects of Russian ground forces, but I never found any online debate over the issue. Interestingly, a few game sites also discussed the deterrent effects of Soviet troops in Cuba.
6) The Economic History Review...
Difficulty: Easy -- On JSTOR
Site: Go to JSTOR within GMU, you can get there by using the journal, title, and author.
7) Find four syllabi...
Difficulty: Easy -- Search "syllabus" and "hamlet on the holodeck"
The hits started to thin out around results pages 13-14
8) 1998 Center for History and New Media...
Difficulty: Difficult -- I still failed.
I know there is a site that captures the major pages of the web from previous years, but I couldn't remember how to do it. After a little struggling, I went to the CHNM website. I found no success there, either. (And, I wasn't very impressed with the CHNM search engine.)
9) Janet Murray and the Sims...
Difficulty: Easy -- First hit.
I used the Image Search and "Janet Murray"
Site: www.thecore.nus.edu/ sts/conf00/murray/talk/5.html
