The e-mails, released Friday by the State of Alaska, begin when Palin took office in December 2006 and run through the fall of 2008, when she was a candidate for vice president. The state released 24,199 printed pages of e-mails; many news organizations began scanning in the e-mails and posting them online Friday afternoon.
About a dozen news organizations requested the e-mails shortly after Sen. John McCain (R., Ariz.) picked Palin in 2008 as his running mate.
The request for the documents came at a time when Palin wasn't only an unknown political figure to most Americans, but also when she had experienced little of the vetting most candidates see in what can be a multiyear bid for the White House.
Their release comes at a time when it's unclear whether Palin intends to run for president. Palin, who hasn't said what she intends to do, has said she has "fire in the belly" for a presidential bid. She also launched a tour of the East Coast in a campaign-style bus emblazoned with the motto "One Nation."
For the most part, the e-mails show a governor deeply engaged in her work as the state's chief executive, including managing the politics of a legislature wrangling over a complicated oil tax proposal she was championing.
Before her first trip to Washington in early 2007 for a meeting of governors, aides suggested Palin meet with Pete Rouse, a Senate aide her advisers described as "chief of staff for a guy named Barack Obama."
"I'm game to meet him," Palin replied.
Family figures such as her son Track are mentioned prominently throughout the e-mails. There's the mundane - a request that the governor's mansion staff have Easter-egg dye on hand. And then there's the more serious, including a lament that state documents about the per diem she collected for working outside of Juneau failed to acknowledge that she was technically on duty the day her son Trig was born.
"I was 'off duty' when I had Trig?" she wrote. "April 18, the day he was born, I signed a bill into law and conducted a few state actions while in the hospital (and that should be recorded for the record.)"
Palin said nothing Friday about the e-mails, although she did mention on Twitter that a new documentary with friendly leanings would see national release in AMC theaters next month. Tim Crawford, the spokesman for her political action committee, SarahPAC, encouraged a read of the documents.
"The thousands upon thousands of e-mails released today show a very engaged Governor Sarah Palin being the CEO of her state," he said. "The e-mails detail a governor hard at work. Everyone should read them."
But long before Palin decried the very "lamestream media" she's now joined as a correspondent for Fox News Channel, she was on the lookout for criticism.
She seemed to be particularly sensitive to the comments posted on the Anchorage Daily News' politics blog. Reading the comments on a blog item left her "puzzled as to the rumors that are able to spread like wildfire," she wrote early as governor.
"Kind of makes my stomach turn over," she told top aides in a Feb. 12, 2007, e-mail.
At one point, she asked that her security team check out one of the most critical commentators.
"I think our security guys should check into her because the times she's blogged about Todd's schedule and what we drive have really infringed on our privacy rights and potential safety when psychos know when Todd's out of town," she wrote July 9, 2008.
Her team was equally sensitive to criticism. On April 24, 2008, Palin's communications director, Roseanne Hughes, asked the top members of the governor's staff to "take action. TODAY."
"Frank and Ivy, if you could get the word out to your contacts - grassroots supporters who love our boss - we need to get them out there FLOODING that Anchorage Daily News Alaska politics blog. I mean FLOODING."
She then offered ideas of what people could say, including "quoting Newt Gingrich that Governor Palin is one of the most aggressive reformers in the country."
Just days before McCain picked her, Palin lamented questions from an Anchorage Daily News reporter about her family travel: "Amazing, the scrutiny we are under . . ."
She seemed to have little idea what was coming. In an Aug. 5, 2008, e-mail, Palin asks staff to find a place in "already-booked-up" Minneapolis, site of the 2008 GOP convention and where she'd make her debut as a national political figure.
