yahoo historical prices webpage vs. pandas data.datareader vs. quantopian data.history

Hi,

I am trying to find (match up) the volume for GE in early may 2003.

The yahoo historical prices webpage and the pandas data.datareader match perfectly.
The quantopian data matches the prices but the volume seems to be off by a random amount.

Has anyone else seen this or know why this is happening?

Thanks in advance,
David
