Welcome to Judaism 101! Judaism 101 is an online encyclopedia of Judaism, covering Jewish beliefs, people, places, things, language, scripture, holidays, practices and customs. My goal is to make freely available a wide variety of basic, general information about Judaism, written from a traditional perspective in plain English.
This web site has grown continually for more than 10 years and continues to be updated periodically. Everything in this web site is free to use or distribute in any way, with three conditions: 1) if you use text, graphics or sound from this site, please credit this site; 2) do not redistribute this information for profit; 3) do not "mirror" this site or copy pages from this site for use on other web sites.

This website is maintained by the Orthodox Union. It is an all inclusive site with many resources. There is a radio station, job board, synagogue network, Jewish calendar, links to articles and resources, support services and much more. I believe the Union is run by a rather large Board of Directors and is updated daily.
From the "about" page: "Mechon Mamre (Hebrew for "the Mamre Institute") is a small group of observant Jewish Torah scholars in Israel who live by the plain and simple meaning of the RaMBaM's Mishneh Torah and actively encourage others to do so.
Most of us belong to the mainstream "Baladi" Yemenite Jewish community, continuing the tradition of living by the Mishneh Torah since the very days when the RaMBaM lived, and are students of the Rav Yosef ben-Dawid QaafiH zS"l (the leading rabbinical expert in recent generations on the teachings of the RaMBaM in general and on his Mishneh Torah in particular). But we have been helped in developing our Written and Oral Torah texts and freeware programs since 1990 by dozens of others from all well-known parts of observant Judaism, including Chasidim and Mitnagdim, Asheknazim and Sepharadim, Europeans and Orientals, both from inside Israel and from all over the diaspora aside from Antarctica (are there no observant Jews in Antarctica who want to help?).
We are currently particularly looking for people to help in adding vowels (niqqud) to the Hebrew texts of Mishneh Torah and the Mishnah, and proofreaders to help us polish the Yerushalmi. If you want to help us in our work, write us! You may also help us by providing financial support for our work.
From the "about" page: "In 1972, the Encyclopaedia Judaica fulfilled the longstanding dream of capturing the full richness of Jewish culture in a single authoritative publication, heralded in the scholarly community as one of the best reference works ever compiled. Nearly 35 years in the making, and the work of the same U.S.–Israeli collaboration that produced the original, the second edition presents the latest scholarship on historic topics as well as extensive new treatments of contemporary Jewish life, including added emphasis of the role of women and explorations of the full global scope of the Diaspora."
