Doctorate is an achievement in Deus Ex: Human Revolution. There are 29 unique eBooks scattered throughout the world in Deus Ex: Human Revolution in addition to the "common" eBooks. Finding these unique eBooks will each provide a 200 XP "Scholar" award and, by finding all 29 of them in one playthrough, you can unlock the Doctorate Achievement/Trophy. Note: The Missing Link DLC (standalone or as part of the Director's Cut) has 5 orange eBooks that give Scholar XP and are copies of the base game's unique eBooks, but these orange eBooks do not count towards the Doctorate achievement.
