If you look at this chapter of a novel in the French language, https://fr.wikisource.org/wiki/Le_Voyageur_enchanté/Chapitre_1 ...it has a link to the corresponding chapter in Russian and next to the word "Русский" is a little arrow ⇔ or <=> If you click that arrow, you get the two texts placed side-by-side, https://fr.wikisource.org/wiki/Le_Voyageur_enchanté/Chapitre_1?match=ru But there is no further matching. Paragraphs are not next to each other. If I understand correctly, this is the "Double Wiki" extension, https://www.mediawiki.org/wiki/Extension:DoubleWiki https://wikisource.org/wiki/Wikisource:DoubleWiki_Extension Is anybody using this feature in a serious way? Does it have any more details that can make the matching better? If both texts had numbered paragraphs and sentences (something like the Bible), it would in theory be possible to match them by number. -- Lars Aronsson (lars(a)aronsson.se) Linköping
