Paladin Press has ceased to exit a few short years ago. Their books are now available from archive.org. One such book is titled "The Safe House: Setting up and running your own sanctuary." I've bought and read the book before Paladin Press went under out of sheer curiosity and I can recommend it. It should really be longer and more in depth but its a good place to start. There is a place to get ALL of the Paladin books, however it is bundled with a lot of very horrific books so I'm giving you the link to a less attractive version that still contains the full-text.

Its still always best to buy books to help the producer of the content, however when it can no longer be purchased anywhere it is considered Fair Dealings.
