BibDesk to Word integrates the popular BibDesk Mac OS X reference manager with Microsoft Word. As an academic, I write many papers; one of my biggest frustrations is the lack of reference support in Word. Although commercial reference managers connect to Word nicely, I prefer the minimalistic and useful interface of BibDesk.
Unfortunately, BibDesk itself is only a reference manager. Including your references in Word is the difficult part. That's where BibDesk to Word comes in -- it finds all citations in your Word document, grabs the information from BibDesk, and formats both the citations and the references section for you.
