Todd Swain, Chockstone Press, 1995.
Swain's all-inclusive guide to The Trapps, Near Trapps, Sky Top, and Millbrook. Route descriptions, photos, quality ratings, and protection ratings. Not as detailed as Williams' guides, but has everything in one volume.
Be aware that the Swain guide, especially, is regularly inaccurate in its route descriptions. Visitors, and even locals, who attempt to navigate via this guide frequently "get Swained". That said, it's extremely convenient to have all the routes for ALL the Gunks areas in a single volume; it's up to the climber as to what they want to carry.
