How do I transfer the bibliography along with a document to another computer?

Hi all,

I made a bibliography database in a LibreOffice writer document that my wife sent me. After getting the stuff done, I sent her the document back but it didn’t transfer the database. I thought it might be incorporated into the opt file but that is not the case.
Any idea what to do?
Is there a special file (the DB maybe?) somewhere I need to transfer too?
thanks for the help!

PS: I use win7-64, she has winXP. Her LO version might be slightly older than mine if that helps.

Under the User Profile location there is a database/ directory. The default bibliography database (biblio.odb) is stored there.

thanks, it helped!
