[Talisman]

I bought the art book and soundtrack but where and how do i access them? i feel like i'm being blind here.

Locate the Steam folder and in it go to steamapps\common\Disco Elysium. There you will find the artbook PDF and two soundtrack folders.

You'd think Steam could do better. On a MacBook I found them here:
/Users/<my-user-name>/Library/Application Support/Steam/steamapps/common/Disco Elysium/Disco Elysium - The Final Cut Soundtrack and Artbooklet
