Q. Will we see these same options in the advanced patron search box after go-live? If so, what are the definitions of each of the categories?

Staff in the Alma system doesn't necessarily mean USM Staff.  We are all technically External Users to the system.  Those Staff accounts are system administrator accounts that are setup for Maine Infonet.  Ideally we should never really have to use that advanced patron option.  Unlike Sierra which you had to put specific characters in to search by, Alma is pretty good a searching by name, peoplesoft id or barcode (or even email address).
