Annals of Carnegie Museum is a quarterly journal that publishes peer-reviewed short and medium-length original scientific contributions in organismal biology, earth sciences, and anthropology, in 40 by 52.5 pica format (168 by 220 mm or 6-5/8 by 8-5/8 inches). Subject matter must be relevant to Carnegie Museum of Natural History scientific sections or Powdermill Nature Reserve (PNR), preferably with connection to the Carnegie collection and/or personnel. Carnegie Museum staff and research associates receive publication priority, but others are encouraged to submit papers, especially those manuscripts explicitly based on the Carnegie collection.
