- An old Langenscheidt's German-English dictionary started to come apart. So far only the page that concludes "statuieren" and begins "Stich" has detached.
- The cover of my copy of Programming Perl came off. (This was about the time that there was news about the more or less stable Perl 6; I resisted the temptation to see an omen and install it.)
Modern bindings can be weak. I lent a copy of Poems and Problems by Nabokov to a friend, with the understanding that she would discard rather than return it if the binding failed. She discarded it. An old Three Famous Short Novels fell apart as I reread "The Old Man" about the time of the floods brought on by Hurricane Katrina. The other week I had a look around the house for Edward Luttwalk's The Grand Strategy of the Roman Empire, but suspected that I had recycled it when the quires came loose. Maybe I and they didn't, but the book isn't here. A few other books show signs of trouble.
This bothers me less than it would have once. A book with its back damaged and leaves coming loose has at least been read.
