Founded in 1971, The Witches' Almanac is a witty, literate, and sophisticated publication that appeals to general readers as well as hard-core Wiccans. At one level, it is a pop reference that will fascinate anyone interested in folklore, mythology, and culture; at another, it is the most sophisticated and wide-ranging annual guide available today for the mystic enthusiast. Modelled after the Old Farmers' Almanac, it includes information related to the annual moon calendar (weather forecasts and horoscopes), as well as legends, rituals, herbal secrets, mystic incantations, interviews, and many a curious tale of good and evil. Although it is an annual publication, its subject matter is timeless-only about 15 percent of the content is specific to the date range of each issue. The theme of Issue 37 (Spring 2018-Spring 2019) is the magic of plants. Also included are the following articles: "Sigil Witchery," "The Witch of Hadley," "SeerStones," "Astrological Plant Remedies," "Pomba Gira," "Coffin Ring," and "Coefficient of Weirdness, Part 2."
