Note: Amazon ASIN 0922558620 features a 2-volume, 2012, annotated edition as "Written and Collected by Matthew Gregory Lewis"; with a description that begins: "Never reprinted in its original form since 1805, and never before presented in a complete annotated, scholarly edition, Tales of Wonder is a landmark in the study of Gothic literature and Romantic poetry."

From the Back Cover (Broadview, 2009, quoted at Amazon.com):
• In the late eighteenth century, Matthew Gregory "Monk" Lewis, a notorious author of lurid Gothic novels and plays, began to gather this collection of horror ballads. Including original and traditional works, translations and adaptations, and even burlesques of the Gothic, this "hobgoblin repast," as Lewis called it, brings together a fascinating assortment of works. Contributors include Lewis, the young Walter Scott, William Taylor of Norwich, John Leyden, and Robert Southey.
• Appendices contain selections from Tales of Terror (1801), a text long intertwined with Lewis's collection; information on Scott's An Apology for Tales of Terror (1799); and parodies and reviews of Lewis's particular brand of Gothic poetry.
