The Doctor's closer to the start of the alphabet, so he ducks around a table and takes a closer look at the 'D' section. The first journal he pulls out is indeed one about the Daleks; loopy circular Gallifreyan handwriting that doesn't quite look like his own, and sketches, specs and specifics on the most effective ways of building close combat weapons against Daleks. For a moment, he stares at the random page he's opened - it's a detailed description of the effects of intensified alpha radiation on the Dalek clone - and then snaps the journal shut, feeling faintly sick. He looked into his other's mind, but it's always a difference between knowing something intellectually, and seeing it before your own eyes. The War really did never end for the other Doctor.

Right. D. D as in drums. He skips the Dalek section - and it's extensive, which he notices with discomfort - and finds the notes on the drums. There are quite a lot of those, too, and as he pulls out one of the folders and takes a look, he's rather lost at first. It looks like his other has made up his own mathematic symbols for these calculations, and yeah, this will take a while, going through these notes. Especially since he's not sure how much of this is relevant - the second journal in the 'drums' section he pulls out is actually a stack of sheet music of Mahler's Kindertotenlieder. Cheerful.

"Should these be in here?" He waves the sheets of paper over his head before he puts them down on a nearby table to be able to continue browsing. As the other Doctor calls out, though, he looks up and quickly catches the object his other threw to him. "What's that - oh."

It's pretty; a small transparent orb with a tiny, golden, moving swirl inside. He's afraid, though, that pretty is all it is. He holds it up against the light. "I don't think this will be enough to run any tests on. Especially not if we want to do more than one test."
