Transcripts of interviews with the late Dolours Price, carried out as part of the Boston College project, have been handed over to the PSNI.
The 61-year-old, who died in January, was part of the IRA gang that bombed London's Old Bailey 40 years ago.
She was one of several former paramilitaries, interviewed by researchers involved in a Boston College project to create an Oral History of Northern Ireland's Troubles.
The PSNI sought access to the transcripts as part of their investigation into the disappearance of Belfast mother-of-ten, Jean McConville, who was abducted and murdered by the IRA.
But the director of the Boston College Project, Ed Moloney and researcher Anthony McIntyre insisted Ms Price did not make claims about the Disappeared in her interviews.
They took what turned out to be unsuccessful legal action to try to prevent the handing over of the interviews.
