I just noticed that two of the books stacked on my desk have flawed spines.
Howie's book says "Semigroup Thoery".
Clifford and Preston's title is upside down.
The midstream font change in Baader and Nipkow is intentional I think, but it's still dumb. It's a good book, but it should have been titled "Term Rewriting." Robert Graves is probably the last person to whom "All That" should be permitted.
