dog ear
1. An oversize, unfolded corner in a publication
caused when a sheet in a pile of paper having a
corner turned under is trimmed in the guillotine.
After trimming, the corner of the defective sheet
extends beyond the trim size of the sheet when the
folded corner is then unfolded. The dog ear is
often useful in early books in determining the
size of the leaf and the sheet because it reveals
the size of the untrimmed leaf. 2. The turned-down
corner of a leaf. See: DOG EARED .
