Where to find the parts numbers of each part of my vw beetle?

I wanted to know the manufacturer parts number of each part of my 2004 vw beetle convertible. Shouldn't there be a list somewhere on the internet?Where to find the parts numbers of each part of my vw beetle?Likely NO there would be 1000's of pages and no one would want to scan and PDF all those pages , There are over 100 Microfiche pages with like 144 pages on each for the beetle

If you want a particular part call the dealers parts department and ask most will give the number over the phone
