  3. By check or US dollars at registration.

Recall that access to our electronic journal PaleoAnthropology is free to all, paid member or not, but your membership fees defray the cost of publishing the journal, as well as travel by students and international colleagues and other expenses, and they are much appreciated. Please check the Society web site for new and updated information on many topics.

You may contact the Society directly by email at jyellen@nsf.gov.
