Sequential numbering of citations across two separate documents

Hi all,

I’m submitting a manuscript to Science (fingers crossed!) and the formatting requires one bibliography for the main text and a second bibliography for the supplementary materials with sequential numbering of citations across both documents. This is across two separate documents, not two sections within the same document. I’ve explored ‘Sections’ in the ‘Output Styles’ but this seems to only address scenarios where two bibliographies occur in the same document. Any ideas before I brute force this and just cut and paste the supplementary materials into the backend on the main text to ensure citations are consecutive?

Many thanks for any advice! I am eternally grateful!

Nic

You can adjust the start number from the bibliography menu, which is openned in Word 2010/13 from the ribbon as shown in the attached snip.
