Journal list

I am presently using BS 10 with Word 2010 on a PC under Windows 7. Biblioscape automatically puts the full journal name in the bibliography while the journal requires the abbreviated name. As an old user of BS (since version 4) I have looked for the journal list to edit it, but I could not find it on the ribbon. I probably need to enter the abbreviated name as a secondary journal name in the bibliography style. But how can I access the journal list? Alternatively, could you suggest a workaround?
Best, Andre
