Unlike rachetta, I'm unable to restore the master list for my bibliography. Up until yesterday it was working fine. There were hundreds of items on the list. As of yesterday, there is only one item listed (the last one I entered). No matter how far back I go on Time Machine, when I restore sources.xml I get the same result - only one item on the master list. When I open sources.xml with a text editor it is clearly not empty and the one item that shows up in Word does not appear to be there. Is there any chance that Word is somehow using a different file - something apart from sources.xml?
