You can freely and lawfully download a printable score for this Work from IMSLP - the Petrucci Music Library - though it may not be exactly the same as the one used to make the Midi Files below, and it probably won't be as good as a proper paid-for engraved and printed score.
There does not seem to be a complete performance of this Work on YouTube. If you know of one, please tell me of it.
Here is a "clickable" Table of the available Midi Files for this Work (note that they are at "baroque" pitch - thus, effectively a semitone below the notes in the Score):-
