The redactions have been criticised by Democrats, who say they violate the transparency law. But the justice department says it has "erred on the side of redacting to protect victims" - what's been withheld and why?
The files shed little light on Epstein's network but intensify scrutiny of the Trump administration's handling of the affair, writes North America correspondent Peter Bowes
Bill Clinton, Michael Jackson, Andrew Mountbatten-Windsor and Richard Branson are among the famous faces in the files - who has been pictured?
Being named or pictured in the files is not an indication of wrongdoing. Many of those identified in other releases have denied any wrongdoing in relation to Epstein
Epstein accuser Maria Farmer, whose 1996 complaint to the FBI is included in the files, tells the BBC: "I feel redeemed... I am shedding tears of joy, but also tears of sorrow for all the other victims"
In the second batch of files, actor Kevin Spacey appears to be pictured twice alongside former president Bill Clinton on a visit to London.
One of the photos appears to show the two posing for a group photo with Epstein's associate Ghislaine Maxwell at the centre. The location appears to be an underground bunker at the Churchill War Rooms.
The other photo - possibly taken on the same day, as members of the group are wearing the same clothes - appears to show Clinton laughing as he moves to grasp Spacey's shoulders.
The BBC has attempted to contact Spacey for comment.
As a reminder, being named or pictured in the files is not an indication of wrongdoing.
Clinton has denied any wrongdoing in relation to Epstein. Last night, a spokesperson said Clinton "knew nothing and cut Epstein off before his crimes came to light".
Late broadcaster Walter Cronkite, known as "the most trusted man in America", also appears to be pictured in data set 3 of the files released yesterday
The photograph appears to show him sitting with Epstein and another man on sofas in a living room environment, with a sandwich tray in front of them. The location is unclear.
Cronkite was a powerful figure in broadcasting, covering major stories like the Vietnam war, presidential elections and the moon landing
He is said to have been instrumental in persuading Lyndon Johnson not to seek re-election for a second presidential term.
When Cronkite broadcast his belief that America could not win that war, President Johnson reportedly said: "If I've lost Cronkite, I've lost middle-America."
As a reminder, there is no suggestion that these pictures imply any wrongdoing.
It is just approaching mid-morning on the eastern coast of the US and as we continue to pore over the thousands of files relating to convicted sex offender Jeffrey Epstein - let's bring you up to date with the key developments in the last few hours:
The US Justice Department (DOJ) has been criticised by senior Democrat politicians after the latest release of files relating to the convicted financier included a number of heavily redacted documents and photographs
Among the images released are some which give a sense of Epstein's jet-setting lifestyle, meticulous record keeping and photos with well-known celebrities including Michael Jackson
Also among the latest newly-published files are images of Andrew Mountbatten-Windsor and former US president Bill Clinton, both of whom deny any wrongdoing
Deputy Attorney General Todd Blanche says there has been "no effort" to redact President Donald Trump's name from the release of the Epstein files
The White House says the Trump administration was the "most transparent in history" as it replied to a court document released by the DOJ on Friday, alleging that Epstein introduced a 14-year-old girl to Donald Trump in the 1990s - you can read more here
Some of Epstein's victims say they feel let down by the DOJ's handling of the material and have called for the full release of all files; one victim, Marina Lacerda, who was abused as a 14-year- old, said a lot of redactions were unnecessary and powerful men were being protected
As part of the partial release of documents in the Epstein files, several books have been either pictured, mentioned or scanned.
It is not yet clear if these books were owned by Epstein, where they have been photographed, or why they have been included in the release.
Among them is a guidebook called Massage For Dummies - which as been scanned and its contents included in the data set. It's also mentioned as one of the "gifts" Epstein gave to a "girl" whose name is redacted.
Elsewhere, three copies of Fire and Fury: Inside the Trump White House, by Michael Wolff, can be seen in a photo from the files.
A previous release of documents by US lawmakers appeared to indicate a correspondence between Wolff and the late convicted sex offender.
Responding to the release at the time, Wolff said: "Some of those emails are between Epstein and me, with Epstein discussing his relationship with Donald Trump. I have been trying to talk about this story for a very long time now."
Deputy Attorney General Todd Blanche says there has been "no effort" to redact President Donald Trump's name from the release of the Epstein files.
On Friday Blanche was asked, in an interview on ABC News, external, whether all documents mentioning Trump in the so-called Epstein files will be released in the coming weeks.
"Assuming it's consistent with the law, yes," Blanche said. "So there's no effort to hold anything back because there's the name Donald J Trump or anybody else's name, Bill Clinton's name, Reid Hoffman's name.
"There's no effort to hold back or not hold back because of that and - and so - but again, we're not, we're not redacting the names of famous men and women that are associated with Epstein."
President Trump has certainly said from the beginning that he expects all files that can be released to be released and that's exactly what we're doing"
