You bring up a good question. Who should get it? I would want it to end in the hands of temporal physicists or anyone who understands what would be a danger if released to the public and what would be a benefit.
Archaeologists, anthropologists and historians can go over items, not be released to the general public, with a fine-tooth comb to get a more detailed picture of the future.
As for what I would include? I have a copy of a journal a friend wrote. I only see one problem if it were published in the past. For time to come full circle, it would be best that he does not read his published journal. If he did, he might not write it.
What else? I would include printed E-mail, drawings by the cartoonist Bill Holbrook and comic books by Terrence and Isabel Marks.
Before the E-mail is published, permission from the author is needed. That in of its self is spooky. Imagine it is the year 1981. You have the CIA in your apartment. They explain why they are there: "We are here to ask questions about E-mail you wrote to Jeanette Isabelle from 2003 to 2009."
"Who is Jeanette Isabelle?"
"She is a girl who will be born on January 26, 1986. You will start an Internet relationship with her in 2003."
If I have room, I would include my DVD collection and a DVD player. Again, I would not have them released to the general public. I want Gene Roddenberry to see them so that his depiction of the future would be closer to being realistic. I also wish the creators of
Back to the Future II would see them so that their representation of 2015 would hit the bull's eye.
I double checked.
Back to the Future II was released in 1989. What if, before the movie starts, they show trailers of films that will be shown in the distant future?

Inside Out movie poster, with Disney's permission of course.
Oh, come on. It would be funny.
The most significant advantage is this will shut the mouths of those who say the world will end, at least a little while. "How can the world end in 2012 if
Inside Out will be released in 2015?"
