As in previous years, this category was write-in only, and this year, we had a tie for first place between long-standing-winner Linux in a Nutshell, by Ellen Siever, Stephen Figgins, Robert Love and Arnold Robbins, and the newly published The Debian Administrator's Handbook, by Raphael Hertzog and Roland Mas. Second place goes to The Linux Programming Interface: A Linux and UNIX System Programming Handbook, by Michael Kerrisk.
