In the The Druid Revival Reader, John Michael Greer has collected 12 writings to represent the Druid Revival.  Some of the texts are by Druid Revival participants, such as Iolo Morganwg and Ross Nichols, while others are by authors who in some way influenced the Revival but were not themselves practicing Druids.  For each, Greer includes a short introduction contextualizing the author and his work and providing a few bibliography entries for further reading; the texts are chronologically ordered, and Greer's forward provides an excellent guide to the collection without imposing too much on the reader in terms of interpretation of the texts.  This is not a text to learn about Druidry as it is practiced today, but it's a valuable resource for learning about contemporary Druidry's roots.  Inevitably, some of the writing is rather dry.  I would recommend this collection to those interested in or practicing Revival Druidry, and to those interested in the historical development of contemporary Druidry.
