An early look at the trove of emails released Friday from Sarah Palin's first two years as Alaska's governor gives an idea of the sudden scrutiny she faced after she was selected as the Republicans' vice presidential nominee in 2008.

Some of the messages she received at the time were blatantly threatening. In one dated Sept. 12, 2008, the sender said Palin should "be shot," using several vulgarities to refer to her. Another email the next day, supposedly from somebody in Belgium, made the same threat.

Other emails in the trove released Friday include questions from reporters and more subdued complaints from the public. In one Sept. 13 email, a Juneau resident said she was "very angry" regarding reports that Palin's husband Todd was involved in official meetings.

A Sept. 15 email from her press aide detailed the topics of the day in the media. Among them was "the tanning bed at the Governor's House" and whether she believes "dinosaurs and humans co-existed at one time."

Palin expressed frustration in response. "Arghhhh! I am so sorry that the office is swamped like this! Dinosaurs even?!" she wrote back, noting she was "dismayed" at the media.

The emails are being combed through by dozens of media organizations. Reporters and photographers crowded into a small office to pick up the six boxes of emails -- 24,199 pages and weighing 100 pounds. Some carried boxes down the stairs and others, wheeling them on dollies, scrambled to be the first ones to reach elevators.

Within minutes of the release, Palin tweeted a link to the webpage for "The Undefeated," a documentary about her rise and time as governor.

Tim Crawford, the treasurer of her political action committee, Sarah PAC, said in a statement that everyone should read the emails. "The thousands upon thousands of emails released today show a very engaged Governor Sarah Palin being the CEO of her state," he said.

"The emails detail a governor hard at work," he said.

Palin resigned partway through her term, in July 2009. Requests also have been made for emails from Palin's final 10 months in office. State officials haven't begun reviewing those records. Sharon Leighow, the spokeswoman for Gov. Sean Parnell, said she doubted the release of those emails would come soon.

The emails released Friday were first requested during the 2008 White House race by citizens and news organizations, including The Associated Press, as they vetted a nominee whose political experience included less than one term as governor and a term as mayor of the small town of Wasilla, Alaska.

The nearly three-year delay has been attributed largely to the sheer volume of the release and the flood of requests.

Alaska is releasing the thousands of emails in paper form only in Alaska's capital city, accessible by only air or water. Reporters from several news organizations arrived in Juneau and made various plans to disseminate the emails to the public.

Palin told Fox News Sunday that she was unfazed by the release of emails, saying there are no more rocks that could be turned over about her life or time as governor. But she also said "a lot of those emails obviously weren't meant for public consumption" and that she expected people might seek to take some of the messages "out of context."

There may not be any surprises to Palin in the emails, however.

Once the state reviewed the records, it gave Palin's attorneys an opportunity to see if they had any privacy concerns with what was being released. No emails were withheld or redacted as a result of that, said Linda Perez, Parnell's administrative director in charge of coordinating the release.

The voluminous nature of the release, the isolation of Juneau and the limited bandwidth in the city of 30,000 people has forced media outlets to come up with creative ways to transmit the information.

It's not clear yet whether the pages being released will contain any major revelations. They will cover the period from the time she took office in December 2006 to her ascension to vice presidential nominee in September 2008.

Prior records requests have shed light on the Palin administration's efforts to advance a natural gas pipeline project and the role played by Palin's husband in state business.

The email release adds another dimension to the vetting of Palin that began in 2008 and comes as she has become a prominent national political figure, attracting large crowds during a recent bus tour across the Northeast.

The emails were sent and received by Palin's personal and state email accounts, and the ones being released were deemed related to state business.

She and top aides were known to communicate using private email accounts. Perez said Palin gave the state a CD with emails from her Yahoo account, and other employees were asked to review their private accounts for emails related to state business and to send those to their state accounts.

Another 2,275 pages are being withheld for various reasons, including attorney-client, work product or executive privilege; an additional 140 pages were deemed to be "non-records," or unrelated to state business.

Some emails may have been previously reviewed in other, earlier public records requests, such as in the so-called Troopergate investigation, in which Palin was accused of putting pressure on public safety officials to fire her brother-in-law, an Alaska State Trooper who was going through a bitter divorce from Palin's sister.
