I'm still adding bookshelves -- this one wraps through the arch between the living room and library/dining room:
Closer look at installation tools: Stanley hand drill, some hex-shank drills, a short-throw "chairmaker's" brace and countersink bit, "Yankee"-type screwdriver, little wood block to help mark holes in the right place, knife-sharpened pencil (a classic Mirado Black Warrior, no less!) and a big pile of clamps to hold it all in place while attaching the new bookshelf to the shelves on each side of the arch.
This is first of two or three for this batch, I hope.
