This (WebSearch 1.11)
search engine has been designed to search through
every page of the online textbook entitled,
Structure, Stability, and Dynamics of Self-Gravitating Systems."
It searches only the pages of this book and, thereby,
serves as an excellent, complete index for the book.
Because this search engine is a perl script running on a Sun Microsystems Sparc2 platform, it is relatively slow. Nevertheless, I think you'll find it very handy. My thanks to Darryl Burgdorf for providing online access to this useful script and to Peter Nelson and John Cazes for helping me implement it.
