As far as I'm aware, this piece is almost universally known as "Nuages Gris", not "Trübe Wolken". I have never heard of this version before, and when I came to the Liszt page looking for the piece, it took me quite a while to find it because of the unfamiliar title. I had to search for "Nuages Gris" as a phrase, and that finally led me to "Trübe Wolken".
So I'm just wondering if the page should be renamed accordingly. M.J.E. 13:16, 3 September 2010 (UTC)
Oh. I hadn't seen that. But does this site have a specific policy on things like this? What is normally done if a piece was originally published under one title, but later on that title has become totally obscure and another has become universal? M.J.E. 13:32, 3 September 2010 (UTC)
For general policy / style guide see IMSLP:Score_submission_guide/Manual_of_Style#Language. I guess in this case we use still the original title as it appeared in the 1st edition. (If a piece is well known under another title a redirect can be created as I did with Nuages gris. Then it can be found easily via the sidebar search function.) If you need more info regarding page titles/specific cases you could ask P.Davydov, he's our chief librarian. Hobbypianist 13:55, 3 September 2010 (UTC)
