This book consists of reprints of readily-available free online articles such as those from Wikipedia about Eugene O'Neill and his plays. This book does not contain any plays by Eugene O'Neill, or indeed anything O'Neill wrote. Hephaestus Books represents a new publishing paradigm, allowing disparate content sources to be curated into cohesive, relevant, and informative books. To date, this content has been curated from Wikipedia articles and images under Creative Commons licensing, although as Hephaestus Books continues to increase in scope and dimension, more licensed and public domain content is being added. We believe books such as this represent a new and exciting lexicon in the sharing of human knowledge. This particular book is a collaboration focused on Plays by Eugene O'Neill.
