In this day and age there are many book sellers, but with Finbarr you can get many easy to follow occult rituals.
Many titles are from Carl Nagal, Marcus Bottomley and a host of other wonderful sorts. Finbarr books is based in Folkestone Kent, UK.
Unfortunely this business is not Internet based at all, due from troll trouble. Also the Owner is a magus himself, and he had no patience to the time-wasters who used to come into his website.
Excellent books, you can google Finbarr books on Ebay, and they sell for more of a price then sold. That is how good Finbarr books are, they are gold dust.

A lovely man called Finbarr O'Malley runs this business, he was a former Catholic and he wore his badge of getting kicked out of church with pride.

The address for Finbarr books is here folks:
