The Canadian Archaeological Radiocarbon ,CARD, is a compilation of radiocarbon measurements that indicate the ages of archaeological and vertebrate palaeontological sites in North America. During the 50 years since the method of radiocarbon dating was invented, archaeologists and palaeontologists have invested heavily in this method, acquiring tens of thousands of radiocarbon dates. These dates represent a substantial financial investment, but their potential for developing the chronology of archaeology and palaeontology remains under-utilized and in some respects misused. The dates are widely scattered in published and unpublished sources, and many have not been reported at all. Furthermore, the dates are not all created equal, as they represent the results of analytical methods and techniques that have evolved over a 50-year period.

This database seeks to improve our understanding and use of radiocarbon dating by compiling and evaluating the analyses. "Building the Database" describes the background, methods, and scope of the database, and it acknowledges the many people who have contributed to its compilation. "Using the Database" provides a short description of the searchable fields and the sequence of pages that can be opened. "Look up a Date" and “Look up a Reference” delivers you directly pages where you specify your search criteria. "Mapping Ancient History" presents the distributions of archaeological and vertebrate paleontological sites in their paleoenvironmental contexts at millennium intervals. Both “Fundamental” and “Technical Aspects” of radiocarbon dating are briefly summarized.
