I want to offer personal recommendations for online accessible resources for the Morrigan, to further help people looking for more material. None of these are necessarily blanket endorsements but these are resources that can be found online, are free, and are worth reading. As with anything else in life remember to use critical thinking and to keep in mind that on this subject there can be a variety of opinions.
Dissertations and Papers - There are some great academic works out there on the Morrigan worth checking out. There are also some that I dont entirely agree with but still recommend because they add important layers to any discussion about this complex deity/deities.
War-goddesses, furies and scald crows: The use of the word badb in early Irish literature by Kim Heijda.
The Mast of Macha: The Celtic Irish and the War Goddess of Ireland by Catherine Mowat.
War Goddess: The Morrigan and Her Germano-Celtic Counterparts by Angelique Gulermovich Epstein.
Demonology, allegory and translation: the Furies and the Morrigan by Michael Clarke.
The Terror of the Night and the Morrgain: Shifting Faces of the Supernatural by Jacqueline Borsje.
Blogs - There are a lot of people who blog about the Morrigan these days and I will admit my own suggestions will be limited to people I know, and read regularly. I dont go out looking around for new Morrigan bloggers because I just dont have time. Youll also note this only includes written blogs, which isnt an intentional snub to vloggers or youtubers just a reflection that I hardly ever have time to watch videos on my pc so I cant recommend them.
Dark Goddess Musings - the blog of author Stephanie Woodfield. Not updated regularly, but has interesting content http://darkgoddessmusings.blogspot.com/
Lora OBrien - Author and Freelance Writer - what it says on the tin. Not Morrigan specific but there are Morrigan posts to be found and Loras writing is always good and worth reading. Lora also offers paid courses on the Morrigan and several other related topics that I highly recommend. https://loraobrien.ie/blog/
Under the Ancient Oaks - the blog of Druid and author John Beckett. Not Morrigan exclusive either, but she is a frequent topic. https://www.patheos.com/blogs/johnbeckett/2017/07/hear-call-morrigan.html
Websites - An assortment of Morrigan related websites out there that I am aware of and whose content is generally reliable.
Scath na Feannoige - Morrigan content and content focused on the warrior path. Some free and some paid access, but excellent material. http://www.dunsgathan.net/feannog/index.htm
Mary Jones Celtic Literature Collective - as advertised, a resource for all things Celtic. Your best source for myths on the Morrigan (in the Irish lit section) and also offering an encyclopedia section http://www.ancienttexts.org/library/celtic/ctexts/index_irish.html
Story Archaeology - A great resource for newer translations of the myths and discussion of the stories in context. If you search the site/podcast youll find multiple results relating to the Morrigan http://storyarchaeology.com/tag/the-morrigan/
Coru Cathubodua - a site by a group dedicated to the Morrigan, with articles and a resource list http://www.corupriesthood.com/the-morrigan/
Artwork - Some of my personal favorite sources for Morrigan artwork I like. Artwork is of course very personal so you may or may not like my suggestions, but either way I encourage you to seek out Morrigan art that speaks to you. I cant list Morrigan resources without including some art, but of course these arent free.
The Ever Living Ones, art of Jane Brideson - http://theeverlivingones.blogspot.com/p/gallery-of-goddesses.html
Ashley Bryner - https://www.etsy.com/listing/114345068/phantom-queen?ref=shop_home_active_3

Dryad Design - statuary and jewelry by Paul Borda - https://dryaddesign.com/small-morrigan-statue/
Books - I should probably mention here that generally I am not aware of any decent books on the Morrigan, specifically, that are available free online. You can access some older public domain works including Hennesseys War Goddess on Sacred Texts but books that old have issues with some seriously outdated scholarship and need to be read with a large grain of salt. They are worth reading with some critical thinking and discernment but I wouldnt give them a blanket recommendation.
PAGANISM & SHAMANISM
What is Paganism? A religion, a spirituality, an alternative belief system, nature worship? You can find support for all these definitions (and many more) in dictionaries, encyclopaedias, and text books of religion, but subscribe to any one and the truth will evade you. Above all Paganism is a creative pursuit, an encounter with reality, an exploration of meaning and an expression of the soul. Druids, Heathens, Wiccans and others, all contribute their insights and literary riches to the Pagan tradition. Moon Books invites you to begin or to deepen your own encounter, right here, right now. If you have enjoyed this book, why not tell other readers by posting a review on your preferred book site.
