Note: There are far too many services that discuss Judaism to list here. The services listed below are perhaps the most comprehensive resource guides to Jewish resources on the Internet.
The "Global Jewish Networking Handbook" was
created by Dov Winer.
The Jerusalem One Server is a very
extensive collection of resources on Israel and the Middle East of
varying degrees of quality (some of the material is excellent and some
is of poor quality). The material is primarily geared to an Israeli or
Jewish audience. Jerusalem One contains: An extensive collection of
News Archives from around the world; An extensive collection of
E-Conferences that deal with such disparate issues as Touring Israel,
the Arab Media, and a Rabinical Question and Answer forum; A collection
of Hebrew Software; A very detailed archive on Holocaust history; A
detailed listing of Israeli and Jewish Organizations world wide;
Information from the Likud Opposition party; and Information from AIPAC,
the Pro-Israel Lobby in Washington, D.C. Zvi Lando is the maintainer.
