This is a picture of my office bookshelf:
I keep copies of all the books we publish on it, so when someone calls to tell me that they need a particular book, right now, there's one on hand we can overnight. It is an excellent bookshelf! But with the amount of books that we're publishing in the coming year (you can see some of those teetering on the edge of the fourth shelf down), I suspect I may have to lobby for a bookshelf expansion.
(Want to see more of the insides of our offices? Here's a piece I wrote for our parent company's blog. There are pictures!)
