The flagship magazines for the educated public published at the Center for Inquiry are CSI's Skeptical Inquirer and the Council for Secular Humanism's Free Inquiry (with a combined readership of nearly 100,000).

Additional magazines at CFI are read in the U.S. (The American Rationalist), United Kingdom (The Skeptic), and Perú (New Skepticism, and The Journal of Applied Philosophy).

Philo is the Center's ground-breaking peer-reviewed academic journal.

There are a variety of electronic and print newsletters for associated membership organizations: Skeptical Briefs for members of CSI, Secular Humanist Bulletin for associate members of the Council; Campus Inquirer for members of CFI's campus outreach program; and SOS International Newsletter for participants in Secular Organizations for Sobriety, as well as The Ingersoll Report, a bulletin of the Robert G. Ingersoll Memorial Committee.

CFI Libraries

At CFI's headquarters branch in Amherst, New York, three unique research libraries share a dramatic reading room, a 70,000 volume collection of books, and hundreds of periodicals, both historical and current.

The John and Mary Frantz Skeptics’ Library and the fast-growing Jo Ann Boydston Library of American Philosophical Naturalism are world-class collections in their respective areas, while the James Hervey Johnson Library of Humanism and Freethought is the foremost such collection in the world.

Holdings focus on the worldwide secular humanist and skeptic movements, archiving local group newsletters and nationally circulating magazines, in addition to the areas covered by the mission of the Center for Inquiry, the Committee for Skeptical Inquiry, and the Council for Secular Humanism.

CFI's research libraries are electronically catalogued and accessible via the Internet and OCLC, the online network linking the catalogues of hundreds of university, college, and special libraries. The specialized collections are complemented by a general reference section. For more information, please visit
