Take the tour ×  I googled the question and found no
explanation. It seems that dog ears are inevitable (for
paperbacks, notably) even if you've always been careful. From my
experience, they are about equally likely to appear on the top
corners as on the bottom corners (for both the beginning pages
and the ending ones). Dog ears for the middle pages of the book
are less likely but they can also appear in frequently used old
books. Can someone explain why?  dog ears on the bottom corners
for the beginning and ending pages  dog ears for the beginning
pages of a book  I apologize if this is not the right kind of
question to post here. I can find no other sites on SE for it.
share|improve this question I think moisture does it. It can
make the paper curl. Also the fact that you turn pages by using
the corners. If you've ever soaked a book in the rain (My copy
of Irodov got soaked once :/ ), then you'll notice that pretty
much the whole book curls up. THough I dunno if this is the
cause. –  Manishearth Apr 10 '12
