The library at Kenwood is one of Adam's finest interiors, and these designs show it almost as executed.

Adam volume 14/114 shows alternative designs for the sofas in the recesses to either side of the chimneypiece, but this may not originally have been the case as the left-hand version has been cut away, and the present version affixed into place. It is this left-hand sofa design that is closer to the executed version. Otherwise, the design was executed almost exactly as shown, but with a little more ornamental moulding on the bookcases. Moreover, the drawing is almost exactly as shown in The works in architecture of Robert and James Adam (1774, Volume I, Part II, plate v), with the left-hand sofa design, but with alternative painted panels, including an alternative overmantel, which in The works is a portrait of Mansfield.

Similarly Adam volumes 14/115 and 14/113 were executed almost as shown. With regard to Adam volume 14/115 the executed curtain cornices are less elaborate, the wall panels to either side of the windows were omitted, and there are narrow bands of moulding above the frieze which are not shown here or in Adam volume 14/113. Moreover, Adam volume 14/113 makes use of slightly different scrolls in the soffits than were executed.

The pier glasses seen in Adam volume 14/115 are shown almost exactly in The works in architecture of Robert and James Adam (1774, Volume I, Part II, plate viii), and the east end of the library, as seen in Adam volme 14/113, is shown in The works (1774, Volume I, Part II, plate vi), but with alternative painted panels.
