There's no website address available yet, but there's an email address at the end of the post. They are still looking for a new Editor-in- Chief, so I guess they may be some way away from launching.
Antiqua is a new, peer-reviewed, Open Access journal intended to archaeologists and scientists having particular interests in the application of scientific techniques and methodologies to all areas of archaeology. Our journal publishes Original Research papers as as well as Rapid Communications, Case Histories, Editorials, and Letters. The journal seeks to provide an international, rapid forum for archaeologists to share their own knowledge.
We are confident that the quality and high ethical standards of our journals can offer a unique service to the international community. Together we can promote scientific advancement and excellence for the benefit of all.
