The Library-Go-Round

The Library-Go-Round adds a distinctive difference to your library, a unique way to show off your favorite tomes and a useful method of conducting research and taking notes. The five shelves of this revolving book display, inspired by one owned by Thomas Jefferson, can hold several books at various levels and angles and are also useful for note-taking and cross-checking information from several sources. The spinning lazy susan-style base of this rotating bookcase is perfect for spotlighting rare first editions, specialty books, favorite artwork and photographs. The Library-Go-Round folds up neatly into a 12" box when not in use.

Abraham Lincoln's law office bookcase

This five-shelf bookcase was once owned and used by the future president in his law office in Springfield, Illinois. Though simplistic in design, it is accented by a thin midnight-blue velvet trim. The two doors of the bookcase are missing.

"The mock bookcase contains real books overpainted in grey with titles borrowed from Hamlet in black. These are titles of actual books by actual authors in order of the apprearance of their words in the play. There must of course be more no doubt being borrowed as I write but these are all that my research has turned up. Most are (rightly I presume) obscure but others are by known writers from Lloyd George to Graham Greene with, most recently, Alan Bennett's Single Spies (Simon Callow suggested, he claims, this brilliant choice of title)."
