Unfortunately my side of the desk in our study gives me the book shelves as background. Thankfully the books on the visible shelves are reports, photocopied articles in carboard boxes, and a mix of books standing on edge as they are too tall for the shelves, interspersed with rather worn secndhand books whose titles are illegible from a distance.
DH has the fireplace beside him that has been fitted with deep shelves containing document boxes with no labels on them, so we are supplied with backgrounds of suitable gravitas, but no one knows what any of the books are or what is in the document boxes - could be empty.
