I don't believe there are any notable, contemporary Nordicist organisations, publications or movements. If you are looking for commentaries or criticisms of older Nordicist works, you could find some of those, but since no new material is being examined there is little reason to prioritise new commentaries over old ones. Keep in mind, also, that recognising differences between Europeans is not exclusively a Nordicist position - Nordicists simply assign particular political importance to those differences.
