The preparation of this review was supported by NSF grants AST 93-18617 and AST 96-17088 and by NASA grant NAG 5-2803. I am very much indebted to W. Dehnen, P. Saha, J. Sellwood, M. Valluri and R. van der Marel who read substantial portions of the manuscript and made many suggestions for improvement. J. Perez and V. Polyachenko also made helpful comments. My understanding of the issues discussed here has benefitted enormously from discussions with A. Bahri, H. Kandrup, J. Binney, G. Contopoulos, O. Gerhard, J. Laskar, J. Meiss, A. Moser, Y. Papaphilippou, and Y. Sinai. Note: imported from RIT’s Digital Media Library running on DSpace to RIT Scholar Works in February 2014.
