Their website is http://www.boardbooks.com/diligentbooks/db-glance.shtml The website will explain what the software does the best.

I do not care if we have to buy something even if it is expensive, as long as it is not a monthly fee and we keep it on our server. Does anyone know if such a software exists that competes with this one.
