I am a high school English teacher, and I am in a graduate program at a state university. This site, hosted by the Berkeley Digital Library is an excellent resource for Jack London projects at all levels of education. In my graduate class, a student presented many creative and obscure items that he located at the website. Many different media genres are represented at this all inclusive site.
The Berkeley Digital Library is hosted and supported by SUN Microsystems and is an official "SUNsite." It is one of the best technically organized sites I have navigated.
