One other thought. Catalogers generally limit themselves to the information on supplied in the notes of a recording. Hence, unless the notes on the disc say something about cuts, versions of cadenzas used, etc. one will not know such things about a recording. Sad to say, significant information can be lost in the process. For example, one would not know that the Toscanini performance of the Barber First Essay differs from the published score.

Well, maybe that is why we have musicologists...Consider Scott K. Colebank's discography of the Rachmaninoff 3rd Concerto. In the edition I have (1997) he lists 115 recordings. Perhaps the most cut version was the Composer's own recording. He did take the regular cadenza. [33:10]. Ashkenazy/Fistoulari by comparison...regular cadenza, no cuts [42:00].
