If you've ever glanced at the cover of a new book and felt a jolt of déjà vu, there's a reason: You probably really have seen that cover before, or at least its main image. Recycling images -- stock art, great art, whatever -- is fairly common in the book design biz.

There are websites aplenty devoted to showing this, and it's interesting to see these covers lined up, side by side (by side). Even when they start with the same basic image, designers can convey entirely different moods through lighting, color and typography.

On one site, you can find St. Paul author Marlon James' recent novel, "The Book of Night Women," next to five other books with the same image. Or scroll up a bit, and see the same model, wearing the same polka-dot dress, same hand clutching the same hair, on Kent Haruf's "Eventide" as on Minneapolis writer Lorna Landvik's "Oh My Stars." (For Haruf's book, she took off her scarf.)
