Many of Tom Jobim's hand lettered scores can be seen at the below link. These really serve as a window into seeing how Jobim's compositions took form and are the originals - before they went to the copyist or publisher! In addition to Jobim's own manuscripts, there are also original arrangements of Jobim material by Claus Ogerman, Nelson Riddle and others who arranged Jobim's melodies located at the same library. Here is the link where you may view them:
