You probably want to start with the SIGGRAPH 1893 Proceedings,
ACM/SIGGRAPH Quarterly, July 1983, "Curve-Fitting with Piecewise
Parametric Cubics", Micheal Plass and Maureen Stone, pages 229-239,
seven figures, 29 reference bibliography, which shows a nice serif'ed
font (from MetaFont (computer modern, perhaps?)) converted back from the
bitmaps to splines. If you have a Citations index handy, this should be
cited in most of the relevant work.
