Actually I'm uploading cover art for "The Rubinstein Collection":
Some of the 82 volumes does not (yet) exist.
I have the cover art and booklets for all the volumes/releases, but I have no idea how to add them for not existing releases.
Can I add such releases without the complete and correct tracklist (maybe adding the release and volume name only)?
What is the best basic work I can do for more experienced user to complete such classical releases?
