Holdem for Advanced players and Middle Limit Holdem Poker are best books about Limit Holdem. Both books are mainly targeted to full ring players, but have small sections about short handed play. Even though those are full ring books every limit holdem player should read them both many times over and over.
In
http://www.pokerpages.com/articles/archives/index.htm there is good articles from Jason Pohl. Look also
http://www.cardplayer.com/ for articles about short-handed play.
I think Slansky/Malmuth or/and Ciaffone/Brier should make book about short-handed play. Problem is that it is much easier to write full-ring limit book than short-handed limit book.
In full ring limit when stakes are not very high you can win without making good adjustments to opponents play. Many winning players only play their own cards.
In short-handed poker you should adapt more to playing style of your opponents and number of players. Every decision depends not only from your cards and position, but also who you are playing against.
