It's a fairly labor intensive process when you figure there are thousands of funds out there and no standardized way of reporting holdings.
Though you would think this would be easy enough for Vanguard to do for their own funds. Perhaps they get the data for all funds from a third party, and the third party doesn't do anything special for Vanguard funds.
Morningstar is arguably the best open source for mutual fund data. Why? Morningstar is in the data business. It makes its money by selling data to users. Many funds and non-fund reference sites quote M* data. I'm sure M* collects a fee. How do they get all this data? The fund companies give it to M* free and in the format M* wants for two reason. 1) No fund wants to have "no data available" on the M* site and 2) M* is not in competition with the funds. There is no way a firm like Vanguard can get the needed cooperation from their competitors to establish a data base like M*'s. Even if they did it might be considered collusion and thus be illegal.
Stop wishing guys. It ain't going to happen.
