The node above contains a broken link to "A Fresh Look at Efficient Perl Sorting." I have located a copy of the paper here: A Fresh Look at Efficient Perl Sorting, by Uri Guttman and Larry Rosler.

In searching for an online copy of the Guttman-Rosler paper, I found another good resource, authored by John Klassa of the Raleigh Perl Mongers, entitled Sorting in Perl.

HTH,
