Thank you for visiting and supporting independent bookstores! 



Ever since we can remember we have looked up to the night sky and wondered about the existence of life in other worlds.  The idea of civilizations in other planets and dimensions was quite natural for us.  News reports of unexplained aircraft and visitors from outer space grabbed our attention and sparked our curiosity from a very early age.

Our deep curiosity about reports of UFOs and other unexplained phenomena turned into a quest that led us to read hundreds of books, travel, and meet witnesses, explorers, and authors from around the world.  In the mid-1980s we joined Arcturus Books Service founder, Robert Girard (1942-2011), in a mission to provide fellow seekers from around the world with a one-stop mail-order book service where they could find a breadth of literature on unexplained phenomena.

After Robert’s passing in 2011, Arcturus Books, which ultimately became ARCSTAR Books, has been run by his wife and her son. They felt it would be best if an organization like MUFON (Mutual UFO Network) bought and ran ARCSTAR. We believe that people need a place to go to get excellent new and used books on the UFO subject. We hope you join us in our journey and become part of the ARCSTAR Books community.
