If you've ever downloaded a copy of a book from the Internet and it was not an authorized copy, read this. There are very few pagan authors who can afford to support themselves fully off of their writing alone. From the post:
Most authors support themselves with full-time jobs in addition to writing and enriching their communities. The very few who don’t work a “day job” have to tour and teach constantly to make a salary to live off of. Some even sell potions, spells, or courses on the internet to add a little income. And yet they still provide plenty of free content on their websites, blogs, facebook pages and other media. They are more than willing to share – up to a point. If they approach a publisher to publish their book, it means, by default, that they want to get paid for it. It has value. So do them a favor and buy their book if you appreciate their work and want to make sure that they continue to write for, communicate with, and teach the community in the future.
