The subroutines from the book "Computer Solution of Large Sparse Positive Definite Systems" by Alan George and Joseph Liu are no longer available via Netlib. They were originally made available as a courtesy so those using the book could avoid typing in the routines. The book has long been out of print, and many of the routines have now been superceded by new codes employing improved algorithms.
