This is a bit pricey, but is a fantastic resource for any fan of Tim Powers. Not only does it feature an in-depth list of all known published editions of his many novels - complete with pictures of the covers in all sorts of languages - but it has never before seen drawings and poems along with huge sections from rough drafts and unpublished novels - all with Powers' own handwritten notes.
Nothing new here - they've been around since forever. But I never had one before so I didn't know how huge they sound. I have two now. I feel like a fucking king with them stacked on top of each other. Now I know why bands play in front of huge walls of them. Even if they're not plugged in, they're pretty nifty to behold.
