In addition to possible delays, the public is also likely to see lots of redactions in any release of new Epstein documents.
In the tranche of files released by the House Oversight Committee last week, names and phone numbers were frequently blacked out to protect privacy.
"Simply letting anything out could reveal a lot of private information that's not relevant or appropriate for public consumption," Prof Entin said.
The latest bill says the attorney general can "withhold or redact" records that include victims' names, medical files and other personal information that "would constitute a clearly unwarranted invasion of personal privacy".
One attorney who handles sexual abuse cases supported Congress improving the provision. But she said releasing the files still might impact Epstein survivors.
"I'm glad in the act itself they put specific language reinforcing the privacy rights of the victims here," said Christine Dunn, co-managing partner at Sanford Heisler Sharp McKnight's Washington, DC, office.
"I'm torn because I think transparency is almost always a good thing, I don't think things change until someone shines a light on them," she said. "But at the same time for the victims, having to relive this in the media is going to be hard."
The attorney general can also withhold classified material and images of sexual abuse.
The justice department already said that a "large volume" of its 300 gigabytes of data from Epstein investigations includes images and videos of minors and thousands of downloaded videos and images of child sex abuse.
Other information in the documents could be protected by grand jury secrecy rules, which the latest bill does not explicitly address.
US Attorney General Pam Bondi said on Wednesday morning when asked about the Epstein files during an unrelated news conference: "We'll continue to follow the law with maximum transparency, while protecting victims."
