A secretary bookcase is a combination of a writing desk with storage above for books or display items (often behind glass doors) and storage drawers beneath.  They were practical pieces of furniture combining beauty and functionality.  The writing desk would drop down to use and often contain small compartments for stationery, ink, pens and blotters.  They could be closed up and locked for privacy of content when not in use.
