• "Palantir"

• Russian

• Published by The St. Petersburg Tolkien Society

• [?1990]: 3 issues in The Tolkien Society archive. The TS was unable to date the issues and estimated them to be from 1990?

• Still active

• Here is the Palantir section of the society website, with links to PDF versions of all 56 issues.

As all issues are in Russian, I don't have a lot of information yet on the contents. Issue #50 (available in PDF form here) is notable in that it has a detailed scan of a handwritten letter from Tolkien.
