Hey there,
i am currently working on Musical-instrumentals. For that I require Full (Conductors) Scores. The only one I have is of Les Miserables. If anyone out there owns a full score and is willing to send it to me or trade it with my Les Mis, please notify me. I have been looking for Scores for months and this forum is sort of my last hope.
Hopefully yours
Jo

If you are looking for scores of modern musicals, I am afraid they are not normally available for sale. People producing musicals rent the score from the copyright owners, for a limited time. It is expensive and not widely available.
