Susan Coll works at Politics & Prose Bookstore and would like to emphasize that this essay should be shelved under fiction. Her novel, "The Stager," will be published in July.

The rules of shelving can seem arbitrary, even arcane, but the fundamentals are easy to learn: two hard covers, and no more than three paperbacks of the same title, on each shelf.  The exception is the face-out. If the jacket is displayed horizontally, behind it you can stack as many books as can fit.

Nina Stibbe’s “Reasons to Be Cheerful” is so dense with amusing detail that I thought about holding the book upside down to see if any extra funny bits might spill from the creases between the page.
