Here is a list of some of the main sources that I use:
- 'Cunning Folk and Familiar Spirits' and 'The Visions of Isobel Gowdie' by Emma Wilby. Two of my top sources, they deal with both early modern witchcraft as well as touching on fairy beliefs and practices.
- 'Popular Magic: Cunning-folk in English History' by Owen Davies. Another good look at early modern magical practices which includes some fairy beliefs.
- 'Between the Living and the Dead' by Eva Pócs. A look at early modern witchcraft practices in eastern Europe.
- 'The Witch Figure' edited by Venetia Newall. A collection of essays on witchcraft in folklore and across different cultures. Quite a bit of fascinating and useful material.
- 'Witches, Werewolves, and Fairies' by Claude Lecouteux. A look at the soul complex within european belief but includes a lot of valuable lore about witches and fairies that is applicable to practice. I found it especially relevant for dream work and journeying.
- 'Scottish Fairy Belief' by Lizanne Henderson and Edward Cowan. Primarily focused on fairy beliefs (and also on my list for that subject) but this book includes a good amount of witchcraft material as well, including some actual methods of dealing with fairies used by fairy doctors and mná feasa.
- 'Witchcraft and Magic in Ireland' by Andrew Sneddon. Not actually one of my favorites as I find the title deceptive - its focus is more on the outbreaks of witchcraft accusations among protestant communities in Ireland. However it does touch to some degree on folk practices and Irish witchcraft in the final chapter so it has its uses.
- 'The Silver Bough' by F Marian McNeill. A look at Scottish folk beliefs more generally it includes some very useful sections on witchcraft and fairy beliefs.
You'll notice there aren't many Irish specific books in there. Well, I haven't yet found a good solid historic text on Irish witchcraft, although I keep looking. For that area I comb through a wide array of Irish specific folklore, anthropology, and academic pagan texts and look at anecdotal material relating to cultural beliefs.
And although I don't really draw on other modern practitioners there are a few who I enjoy reading or have found thought provoking or useful*. Not all of these are people who necessarily consider themselves witches, per se, and they aren't necessarily people I agree with 100%, but they are writers I think are worth considering. For that list we'd have:
- 'A Grimoire For Modern Cunningfolk' by Peter Paddon. Peter was a great guy and I enjoy his writing style and approach to the subject.
- 'Call of the Horned Piper' by Nigel Jackson. One of my favorites for modern traditional witchcraft, I found it really resonant.
- 'Essays From the Crossroads 2016 Collection' by Seo Helrune. So I admit I'm a big fan of Seo Helrune. Love this book, love the blog (which you can find here). More focused on ancestor work than I am but very insightful and deliciously blunt and willing to confront hard truths.
- 'A Practical Guide to Irish Spirituality' by Lora O'Brien. Another of my favorite books, not witchcraft specific exactly but full of good material, much of which I find touches on actual practices. I also enjoy Lora's blog which can be found here
Speaking of blogs:
- Sarah Anne Lawless has a great blog here that I very much enjoy and recommend. I don't agree with everything she says or all her conclusions but I love her perspective and find her material always raises good points (even when I disagree).
- Via Hedera - a great blog looking at green witchcraft, animism and generally interesting witchcraft related subjects. Not exactly tradcraft but lots of great food for thought in related practices.
So that covers all the main things I can think of. Some books and some blogs, some academic some personal, a mix of material. When it comes to my own practice I look at these resources as well as the body of fairylore that we have, see what works and what doesn't through experience, and go from there.
*I am aware that there are many other books on the market in the genre of traditional witchcraft. Generally speaking I have either read them already and they just didn't resonate with me, or I haven't been able to get a copy yet (Gemma Gary is on my wish list for example).
