Notes

Two versions of experience boosts are found in-game with the same name and icon -- however with different Tool-tips (i.e. effects)!
The current version available for purchase is known as: Tome of Extraordinary Experience

Enhanced XP Supplies are found in those gift boxes you get for reaching certain levels as noted above.
Neither item provides a benefit if you are at the level cap (150).
While the basic effect is the same, the duration of the effects are slightly different.
- The Tome of Extraordinary Experience gives the Tome of Extraordinary Experience effect which lasts for one hour.
This effect applies to all enumerated items during that time period.
- The Enhanced XP Supply adds a blue XP bar on your XP bar, very much like the VIP daily XP bar.
The amount of bonus XP granted is equal to 1/3 the amount of experience required to reach the character's next level. This bonus is only consumed as you acquire experience similar to the bonus for Reputation Experience Small Reputation Acceleration Tome or Reputation Acceleration Tome and therefore persists across login sessions, i.e. it is not timed.

Changes in Update 14

Update 14, The Paths of the Dead - July 14, 2014 - from the release notes:

Welcome Back Weekend

The Welcome Back Weekend effects have been updated to now grant a % bonus to Experience Gain on Monster Kills, Crafting, Quest Completions, Legendary Items and Mounted Combat XP.

Changes in Update 11

Update 11: Treachery of the White Hand - May 2013 - from the release notes:

Enhanced Experience

Rest experience is getting an overhaul! Basics: Rest Experience is becoming Enhanced Experience.

There will be two kinds of Enhanced XP: VIP Bonus XP and Store item Bonus XP.

VIP Bonus will appear blue on your experience bar. Store Bonus will appear as light blue. Bonus experience will apply to all basic forms of experience (adventure XP, legendary, steed, etc.). If both the VIP bonus and the Store bonus are present, the VIP bonus will be used first. Store Experience boosters, like the Tome of Extraordinary Experience, can be used along with these bonuses.
