Carl Llewellyn Weschcke, a young Saint Paul, Minnesota publisher, saw the Llewellyn company listed for sale in Publishers Weekly and purchased it in 1961, relocating its operations to Minnesota and beginning a decades long expansion of its catalog well beyond George's original astrological focus. Under Weschcke the company became one of the principal English language publishers for Wicca and contemporary Paganism, psychic development, tarot, alternative healing and the broader New Age movement that grew rapidly from the 1970s onward, publishing many of the movement's most commercially significant authors and helping popularize practical, how to style occult publishing for a general audience rather than the more academic or fraternal lodge oriented publishing that had dominated the field earlier in the century.
The company retained and continued George's original astrological line, including the Moon Sign Book and a growing annual almanac series, alongside its newer subject areas, giving it a catalog that spanned the full range of popular astrology and neopagan and occult publishing by the century's end. Now based in Woodbury, Minnesota and still under Weschcke family ownership and leadership, Llewellyn Worldwide remains one of the largest specialist publishers in its field, marking more than a century of continuous operation since its 1901 founding in Portland.
