The IRA was called on yesterday by the Government-appointed Victims Commissioner, Mr John Wilson, to identify the burial sites of victims whose bodies have not been found.
Mr Wilson, who has formally begun his work following his appointment in May, said it was extremely important for victims' relatives to be able to give family members a proper burial.
He said he did not mind whether the IRA disclosed the location of bodies or passed on the information to him, but he would go "wherever is necessary" to get the information.
The former Tanaiste and Cavan-Monaghan TD said advertisements would be appearing in the national press and in local papers in the Border counties of the Republic over the next few days publicising the commission and giving its telephone and fax numbers and an email address.
Interested groups or individuals would be invited to contact the commission and possibly meet him to make submissions.
"I know that many victims feel that they have been forgotten and that no one is listening to their stories. I sincerely hope that I can give them a voice," he said.
Mr Wilson's appointment was announced shortly after the British government-appointed Victims Commissioner, Sir Kenneth Bloomfield, reported on the measures needed to recognise the suffering of victims of Northern Ireland-related violence.
The feeling of isolation of many victims of violence, identified by Sir Kenneth in his report, was shared by victims in this jurisdiction, said Mr Wilson.
He said the Taoiseach, Mr Ahern, had pledged then that the Government would, in consultation with the victims themselves, consider what further steps should be taken to address their particular needs.
"This commission is a first step in that process."
