Academic Info: Philosophy — Directory of Online Resources
Divides links into general, reference, ancient, medieval, modern, existentialism, mind, African, Chinese, and Indian. Would be useful for research for students, especially the last few, and for teachers to begin some basic research for class lectures and readings.
The Window: Philosophy on the Internet
Link-based site with some very short bios on major philosophers and a small timeline. Links include research resources, online texts, other sites, universities, and journals. Somewhat useful for students at very beginning of research and for teachers. Best feature is the links pages.
