Jewish learning source material online

As we are in the period between Rosh Hashanah and Yom Kippur, it seemed to me a good idea to post a list of primary sources of Jewish learning available on the Web in English and Hebrew. I am not interested in listing every site that has divrei Torah, as there are hundreds of them already - just places where you can find source material. It is listed on the sidebar as "Source Materials for Jewish Learning;" here is what I have so far:

• Snunit - Hebrew Tanach, Talmud, Mishneh Torah
• Mechon Mamre - Tanach with nikudot and English, Talmud, Rambam
• Hebrewbooks.org - PDFs of seforim
• E-Daf - images of every Talmud page
• Seforim Online - PDFs of seforim
• ORT - Chumash and Haftarot with trop audio, English translation
• Tachash - English Chumash with Rashi
• Wikisource Hebrew Mikraot Gedolot (in progress)

If you have any other primary sources appropriate for learning, please let me know; I'll be happy to maintain this list.

G'mar chatimah tovah!
