If you can understand the written word in German, Italian, Portuguese, or Spanish -- you can help. Oh, you will also need to have access to a copy of Insight on the Scriptures (it).
Insight on the Scriptures was first released in English, at the “Divine Justice” conventions. The actual release of that two volume set began on Friday, June 17, 1988.
According the the Kingdom Ministry, release dates of foreign language editions are as follows:
German 11/90; Italian, 12/90; Portuguese, 2/91; Spanish, 11/91.
It would be of great help for you to look up the following 5 articles: Destruction, Repentance, Sodom, Gomorrah, and Judgment Day. The following are quotation snippets of those articles in English, all which clearly show that some inhabitants of ancient Sodom and Gomorrah will receive a resurrection.
It's important to know whether that understanding carried forth into the foreign language translations of that publication or if, when, and in which language they reversed their understanding to what it is today -- no resurrection for those ancient ones.
I have no idea whether the Society provides their Library on CD for those languages. If so, please clarify where you're getting your information -- hard copy or CD.
*** it-1 p. 616 Destruction ***
This is also illustrated by what happened to the cities of Sodom and Gomorrah and their inhabitants. Jude indicated that these cities were everlastingly destroyed. (Jude 7; compare 2Pe 2:6.) However, Jesus’ words recorded in Matthew 10:15 show that at least some of the inhabitants of Sodom and Gomorrah will receive a resurrection.—See JUDGMENT DAY.
*** it-1 p. 985 Gomorrah ***
Though the cities underwent “the judicial punishment of everlasting fire” (Jude 7), Jesus indicated that people of Sodom and Gomorrah would experience a resurrection to stand for judgment.
*** it-2 p. 137 Judgment Day ***
This projected the matter into the future and naturally suggested that the people of Sodom and Gomorrah would then be alive by means of resurrection.
*** it-2 pp. 775-776 Repentance ***
By contrast, the people of Sodom and Gomorrah as well as those of Canaanite Tyre and Sidon are spoken of by Jesus as finding “Judgment Day” more endurable than would the people of certain Jewish cities. (Mt 10:14, 15; 11:20-24) Those of pagan Nineveh are similarly spoken of. (Mt 12:41) This of itself implies that people from all such places, including the Jewish cities mentioned, will be resurrected and have opportunity to manifest humble repentance and “turn around” in conversion to God through Christ.
*** it-2 p. 985 Sodom ***
Sodom and Gomorrah were everlastingly destroyed as cities, but this would not preclude a resurrection for people of those cities.
