I'm adding a Second Edition Preface to this book and would like to match the original font. For what it's worth, the book is The Impact of Intervention by Bruce J. Calder, University of Texas Press, Austin, © 1984.
Identifont says the font is Elmhurst, but I don't think that's quite right. I'd also appreciate suggestions of fonts which are close.
P.S. Sorry about the distortion created by the lens of my digital camera. I don't have a scanner.
