Search terms

The two primary keys for data retrieval are the DOI of a publication or the labcode of a radiocarbon date. Other searches will be indexed by the major search engines and specific search facilities will be added to this site.

Example usage

This site is designed for RESTful data access. URLs are used to retrieve or display data. The suffix used determines the format in which the data is retrieved. The following are examples:
