The shorts featured on this DVD are:
Your Friend the Rat [Initially Included with Ratatouille]
Presto [Initially Included with Wall-E]
Burn-E [Initially Included with Wall-E]
Partly Cloudy [Initially Included with Up]
Dug's Special Mission [Initially Included with Up]
Day and Night [Initially Included with Toy Story 3]
Toy Story Toons : Hawaiian Vacation
Toy Story Toons : Small Fry
La Luna [Initially Included with Brave]
You can also find the animatic-like "George and A.J" [From the Up universe] and a couple of Mater's Tales toons "Air Mater" and "Time Travel Mater" [set in the Cars universe]. Additional bonus shorts are four student films that were created by directors at Pixar.
Don't expect to find just 3D animation here. "Your Friend the Rat" and "Day and Night" employ 2D animation techniques as well. This is a real treat for animation fans and animators alike, with insight via both commentary on every single short and the pencil tests of some of the student works.
With all this praise then, why am I saying this DVD probably -isn't- a good idea for true blue Pixar fans to buy? Namely, if you're really into their stuff, you more than likely own every movie they've made. And bar the Toy Story Toons (which I don't know whether they were included on any DVDs) and the Mater shorts (which ended up as part of a separate compilation), all these shorts have shown up as bonuses on the DVDs of the movies that they're associated with. Essentially, you'd just be buying a copy of something you already had.
The student films are a nice touch, of course, but with a (currently) £10 price tag, unless you're like me and don't own all the movies, you might wish to wait until the price drops, rent it or avoid it altogether, because you could end up disappointed.
