A wealth of woodworking information, including tool reviews, a searchable database of woodworking articles--and even a database of articles about woodworking accidents.
A clearinghouse for information on woodworking for woodworkers, it includes woodworking websites, forums, blogs and other online resources. A good site to browse if you have some time. Published by the August Home Publishing Company, which also publishes the magazine, Woodsmith
"Traditional woodworking resources on the web". A good site for those interested in older, more traditional woodworking tools -- how to find them, restore them, and more. "Electronic" refers to how you find the information, not how the tools are powered.
