The Libation Library is constantly expanding and currently includes the following books.  (This page is still under construction)

My first book that started me down the path of learning about liquor and cocktails:

• Vincent Gasnier, Drinks (2008)
  

Other books that I believe in which one should invest to start a library (I often use these books for general reference or cocktail recipes):

• Robert Hess, The Essential Bartender’s Guide (2008)
• Ted Haigh, Vintage Spirits and Forgotten Cocktails (2009)
• Brad Thomas Parsons, Bitters: A Spirited History of a Classic Cure-All (2011)

A great book to build your historical knowledge from a master cocktail historian:

• David Wondrich, Imbibe! (2007)
