Another clearinghouse, the National Clearinghouse for ESL Literacy Education in Washington D.C., is also comprehensive.

The ESLoop's list of sites is organized as a ring and encourages submissions of other relevant sites by viewers. (The ring structure assures that all links will be accessible, even if a URL is changed.)
