The NLA, which is owned by the newspaper industry, announced plans to radically overhaul its service in June (PRWeek, 24 June), with eClips being rolled out from September .
The service means cuttings agencies have to use a digital database rather than scan newspapers as they previously did.
But the CIPR has condemned the move amid fears of rising prices, lack of confidentiality and censorship.
'The NLA is not prepared to move on any of the issues that concern us,' said CIPR head of public affairs Francis Ingham.
Ingham added that he was unable to forward complaints from CIPR members to the NLA because the complainants had requested anonymity. However, NLA MD Martin Stevenson said he was 'genuine' in offering to work with the CIPR to find a resolution.
