No, that cannot be done. Depending on the referencing format you're using, a citation might look like 'Shakespeare, W' and the bibliography entry might look like 'Shakespeare, William'; neither will give you 'William Shakespeare' unless you tell Word the surname is 'William Shakespeare', in which case both the citation and the bibliography will depict it that way.

Thanks - but what I need is, precisely, 'Shakespeare, William' in the bibliography whereas the text will obviously allude to 'William Shakespeare' ... Why is this impossible? Thank you again for your help.

Because that's how any given referencing format works; that's not something under Microsoft's control. That said, Microsoft's implementation is abysmal for some referencing formats, especially Chicago.

Thanks for your help on this, but so far as I can tell there is no alternative to doing these inversions one at a time by hand (???)
