My links

My five links are to :

• The class website;
  
• The department website (or, the old department, I guess);
  
• A collection of historical maps;
  
• An interactive "google-maps"-type tool that allows you to see recent crimes in a given neighborhood, zip-code, or anywhere(just zoom in)-- I call it "Crimes Maps" on the links list there.
  
• American Factfinder, to find information.
