The NGGJ Encyclopedia relies upon the contributions of scholars and lay people who wish to bring in their experience and knowledge of Ashkenazic Judaism for the period of 800-1300. It is designed to be constantly updated, so that it always reflect the current state of research. Cooperating is simple:


You create a free user account and optionally provide additional information to your user profile. Why do I need to register?


You found one or more locations in the index you would like to work on? Most often, you may just start writing. Sometimes, it might be a bit more complicated.


Your input makes the difference in order to further develop the NGGJ. Others can benefit from your knowledge, be it for their own research or to update other articles. Furthermore, we make sure that your rights as author are protected. How does that come about?
