Anonymous Patron writes Keeping Tabs: How many college students today ever flip through trays of library catalogue cards? Some of them may never have used an actual tabbed file. But the tab as an information technology metaphor is everywhere in use. And whether our tabs are cardboard extensions or digital projections, they all date to an invention little more than a hundred years old. The original tab signaled an information storage revolution and helped enable everything from management consulting to electronic data processing.”
