Leonardo da Vinci 1452-1519: The Complete Paintings & Drawings, written by Frank Zollner and Johannes Nathan, has been republished by Taschen in a single-volume folio edition with a slipcase (which folds into a book stand). It was originally published in a slightly larger format, and subsequently reissued in two smaller volumes (The Complete Paintings and The Graphic Work, the latter also available separately and with the alternate title Sketches & Drawings).
The book's title is misleading, as its collection of 663 Leonardo drawings is incomplete, though the selection is still impressive. (It was also released with the alternate title Paintings, Sketches, & Drawings.) Most of the drawings are from the Royal Collection at Windsor Castle. The book (translated from Leonardo da Vinci: Samtliche, Gemalde, & Zeichnungen) also includes a catalogue raisonne of Leonardo's paintings and a new chapter on his codices.
