Then maybe I should elaborate.
My 4 favorite things out of that would be the 2 sets of plans and the 2 Titanic: The Ship Magnificent volumes.
The GA plans give detailed information on Titanic's interior, going deck by deck at a 1/350 scale, covering room shapes and furniture arrangement.
Rigging gives a starboard view of Titanic and primarily covers her cables and wires.
Titanic The Ship Magnificent Volume One covers Titanic's exterior materials and looks, in addition to a small amout on her construction. It weighs in at 688 pages.
Volume Two is more for interior, covering room designs, door knobs, bath tubs, shower heads, toilets, recreational areas, staircases, paneling, styles, materials, (off the top of my head) and more. It's 512 pages.
NOW you can see how I landed a spot as Bones4's primary research support, in addition to a copy of his Titanic along with her hatch covers, lifeboats, and color pallette, all of which were emailed to me by the man himself.
