An alphabet of SMALL CAPITAL LETTERS available in most Roman type faces approximately the size of the lower case letters.  Used in combination with larger capital letters.
Smudge Resistance:
Resistance of a freshly printed surface to ink blurring or smearing.
Smyth Sewing:
A method of fastening side-byside signatures so that each is linked with thread to its neighbor, as well as saddle-sewn through its own centerfold.  Smyth-sewn books open flat.  The stitching is on the back of the fold.
