Does the system have a way of your requesting them to purchase the book?

Yeah, but it takes a lot longer than I'd like it to get done. I put in orders for both Off The Rails and My Appetite for Destruction about 6 months ago and they just came out a few weeks ago as you can see since those are the most recent books I've been reading. I'll do the same for Steampunk but it will probably take even longer to make its way here because it's not a high priority book like the others.
