The essays in Foragers and Farmers of the Early and Middle Woodland Periods in Pennsylvania reflect a range of recent thought and research on what Paul Raber describes as one of the most "enigmatic periods of Pennsylvania's prehistory." The essays represent a variety of viewpoints and approaches to the period, from the site-specific to the synthetic, and they include evidence from all parts of the commonwealth. Together, they define the principal themes and issues in Early and Middle Woodland studies and show a variety of ways in which researchers in Pennsylvania are attempting to address them. The issues outlined in Foragers and Farmers offer a framework in which continuing research on this period can contribute to the broader study of some of the major questions in archaeology. Along with the editors, the contributors are J. M. Adovasio, Kristen A. Beckman, Thomas C. East, R. Fryman, Janet R. Johnson, Michael Klein, Mark A. McConaughy, D. R. Pedler, A. G. Quinn, R. Michael Stewart, and Andrew Wyatt.
