Weblinks needed for open-air museums

EXARC (in cooperation with OpenArch) is preparing a little guide for archaeological open-air museums. It will explain what this category of museums can learn from the international museum world and where to find this help.We are 350 in Europe and maybe 1,000 worldwide and need contact with museum professionals.

Included should be a shortlist of weblinks to organisations where archaeological open-air museums can get advice or recommendations.
This list should NOT include the usual national museum organisations but for example specialists in museum shops, in museum education and such - it does not matter in what country as long as they understand English.
Of course we will include links to several IC’s and AO’s of ICOM but what ELSE is there for open-air museums like us?

Tips to include in our shortlist are welcome at, please before 15 October 2015.
