Bach Societies

[Albert Z.]

Does any one know nice & rigorous "Bach Societies" to become as a
member? I mean serious ones with a periodical well-based publication.
American Bach Society or the london one perhaps? I'm from Spain,
though, but anyway please are there any others?

(Bach-Archiv's Bach Magazin is only written in German as far as I know)

Thanks!

Neue Bachgesellschaft is fine I see but I'm not sure if their
publication, the "Bach Jahrbuch" is written in English
