From Poynter Online:

A 2004 Neiman Report [PDF] on cartoonists said that 10 years ago, there were 150 salaried editorial cartoonists in America. Now, the report said, there are about 85 left. I have seen other estimates -- all of them lower. The report includes interviews with a number of publishers, explaining why editorial cartoons are important.

What makes a great editorial cartoon? What are the most memorable cartoons from your town?

 

Daryl Cagle's Web site not only includes links to the cartoons that have caused so much pain and furor but it includes cartoons about the cartoons. The site includes a lesson plan for teachers (elementary through high school) who want to talk about free speech and editorial freedom. 

The American Association of Editorial Cartoonists also has a Web site that includes an official statement about free speech. The site includes a large collection of cartoons. The AAEC has a large collection of historic cartoons, as well.
