1. Differential Geodesy by Martin Hotine, Springer-Verlag, Berlin-Heidelberg-New York (1991) 202 pages. This is a collection of selected unpublished papers of Hotine dealing with differential geodesy. I served as editor and wrote commentaries on each of the twelve items included in this monograph.
2. Foundations of Differential Geodesy, Springer-Verlag, Berlin-Heidelberg-New York (1994) 374+ pages. This is advanced graduate text/research monograph on theoretical geodesy which is a culmination of my work on differential geodesy since 1986. About 70% of the material is new research which has not been previously published.
