Batch Geocode
This free and easy to use service allows you to enter multiple addresses, geocode them in bulk rather than on at a time, and display them on a customizable map. BatchGeocode.com uses Yahoo's Geocoding API.

Google Maps
Use Google Maps to map your favorite places, draw lines and shapes to highlight paths and areas, add your own text, photos, and videos, and share your maps. See Google's Create a Map video. Additionally, you can add to your maps content and gadgets created by others. One of our favorite gadgets is the Position Finder tool, which allows you to click on the map and get latitude/longitude coordinates in decimal degrees.

Google Earth
For more extensive mapping options, such as satellite imagery, terrain, 3D buildings, and even galaxies, see Google Earth. You will need to install this free application on your computer.

KMZ Census Mapper from the University of Tennessee
"This site allows users to create KML files for mapping Census 2000 data for Census Tracts, Zip Code Tabulation Areas, and Counties. The KML files can be used in programs such as Google Earth and ArcGISExplorer, or, if not too large they can be viewed directly in Google Maps."

Google Spreadsheet Mapper Tool
This tool allows you to create placemarks in Google Earth and Maps using data entered into a Google Docs spreadsheet. The Mapper Tool provides several balloon designs to choose from, or you can follow the directions to design your own using the HTML template system.
