i have about 88,000 songs in my music library, some are duplicates. Does anyone know of any Apple Product or 3rd party software that will identify and remove duplicates.

Backup your music to an external source before doing this, just in case you delete the originals by accident.

iTunes will show you the duplicates. But I recommend tagging their comments or another field once selecting them to ensure you don't accidentally delete both the original and duplicate. You can always select all of them and change all their comment tags at once. Once you've done that, stop showing duplications, and then sort by the comment field. This will allow you to determine whether only the duplicates were shown in the show duplicates, or the originals. If you see any without comments, then you can go ahead and delete the duplicates.

Note, I don't know how you ended up posting to the 10.3 forum, but Mac OS X 10.3 will not run on MacBook Pros. To find your Mac OS X version, go to Apple menu -> About This Mac, and in the future please post the forum more closely resembling your issue. I've asked the moderator to move this thread to the correct forum.
