Advances in Entrepreneurship, Firm Emergence and Growth provides an annual examination of the major current research, theoretical and methodological efforts in the field of entrepreneurship and its related disciplines, including firm emergence and growth research. The Advances series also publishes papers from other fields, such as strategy, organizational behavior or sociology, that use entrepreneurial samples or make a contribution to entrepreneurial theory or research. It is a key source of articles-of-record for major concepts in the discipline of entrepreneurship.  Volume 20, Reflections and Extensions on Key Papers of the First Twenty-Five Years of Advances, is the first in a two volume collection  that celebrates the series' anniversary and embodies the idea of "past as prologue." This first volume showcases some of the most important and well-cited papers from the series including works by Dean Shepherd, Zach Zacharakis, and Connie Marie Gaglio. Reflections on their original works by each author as well as commentary by rising scholars of today are also included. The volume demonstrates the timelessness of the original classic works and demonstrates how they connect and energize leading-edge contemporary research in entrepreneurship today.
