The strains of classical music float through the Seven stars bookstore in Central Square, quietly weaving past the comfortable armchairs and the clerk reading at the checkout desk.

While everything about the store suggests that it is just another outlet for the latest Tom Wolfe novel or a Harvard professor's literary critique, a glance at the shelves quickly proves otherwise.

Lined upon the walls are Anarchy magazine and Indigenous Woman.

Not exactly your usual lineup of Newsweek and Time.

That's because Seven Stars is an "occult bookstore," according to longtime clerk Phillip Johnson, and it sells everything from tarot cards to gemstones.

Its specialty, though, is books.

Interested in UFOs? You can catch the latest from Whitley Streiber, the author of the Communion series. Streiber claims he was abducted by aliens on December 26, 1985, while vacationing in upstate New York.

If something more direct is to your taste, Seven Stars also carries The Ultimate Alien Agenda and The Idiot's Guide to Extraterrestrial Intelligence. Or you could browse through one of the many books on Roswell, New Mexico, the site of a purported UFO crash.

However, the store also caters to those with more earthly desires. According to Johnson, the best-selling book at the moment is Multi Orgasmic Man, a book on helping men improve their sexual technique.

"That book sells like hotcakes," Johnson says.

Johnson's comment causes a tall man with spiky blond hair to pause on his way out of the store.

"Yeah, I just bought that book the other day," the customer affirms.

Beyond extraterrestrial life and how-to books, Seven Stars has many other types of books.

The store has a religion section, including shelves on Hinduism, Islam and Taoism.

There is a section on women's studies, as well as two shelves devoted to astrology that dominate the store.
