Former US president Jimmy Carter is sending observer teams to Libya to monitor and report on that country's July 7 parliamentary elections.
Mr Carter said in a statement that he hopes the centre's limited mission will contribute "to a peaceful, transparent and credible electoral process and will support Libyans' aspirations to build a strong democracy".
Voters will elect a national assembly that is expected to write a new constitution for Libya.
The election will be Libya's first national vote since the capture and killing of long-time leader Muammar Gaddafi last October.
The Carter Centre said security will restrict deployment of observers in some areas. Consequently, it said it will not offer a comprehensive review of the election.
The centre was invited to observe the election by Libya's election commission.
