The items remain per the Main FAQ (p91).


  What happens to a summoned monster’s equipment when it dies or the spell ends? What if it’s not carrying the equipment any more? What if
  it’s carrying something new? When a summoned creature goes away, so
  does everything it came with. If it’s holding or wearing something it
  didn’t appear with, that item drops to the ground in the creature’s
  space after it disappears.


The only arguement (besides Main FAQ haters;)) I can see here is if you believe "spell ending" and dismissing the spell are different but I believe they are the same.

Can summoned creatures take items back with them?
I need guitar chords in a database for a project I'm working on ( preferably MySQL, CSV or some other easily portable format ). I can imagine many formats by which one could store this information, so I don't particularly care how it's setup.

This information must exist in databases all over the internet, but is there anything freely and publicly available?
