What was advertised in a colonial American newspaper 250 years ago today?

“Just published … Father ABRAHAM’S ALMANACK.”
It was one of the signs that fall had arrived in the colonies: advertisements for almanacs began appearing in newspapers from New England to Georgia. The appearance of these advertisements had a rhythm as familiar as the changing of the seasons. A small number appeared as early as July or August to announce that particular titles would be published in the coming months. A greater number ran in September and October. By the end of October, some printers informed customers that they had just published almanacs, alerting them to purchase their favorite titles before supplies ran out. In November and December the number and frequency of advertisements for almanacs increased. As the new year approached, printers devoted significant space to newspaper advertisements about almanacs. This continued into January, though the advertisements tapered off in February and beyond. Some printers continued their attempts to rid themselves of surplus copies that ate into their profits. By the time spring arrived, advertisements for almanacs practically disappeared.
John Dunlap inserted his own advertisement for “Father ABRAHAM’S ALMANACK, For the Year of our LORD, 1770” in the October 16, 1769, edition of the Pennsylvania Chronicle. Noting that he had “Just published” the almanac, Dunlap made it available to customers two and a half months before the beginning of the new year. His marketing strategy consisted primarily of listing the contents, hoping to entice prospective customers with a combination of practical reference materials and entertaining essays and poems. The almanac included the usual astronomical calculations, such as “the Rising and Setting of the Sun; the Rising, Setting, and Southing of the Moon; … [and] Length of Days.” Other reference material included “Tables of Interest at 6 and 7 per Cent; a Table of the Value, and Weight of Coins,” and a calendar of “Quakers yearly Meetings.” The practical information even extended to medicine: “A Collection of choice and safe Remedies, simple and easily prepared.” Dunlap imagined some of his prospective customers when he suggested that these remedies were “fitted for the Service of Country People” who did not have immediate access to apothecary shops in Philadelphia. The pieces of entertainment included “An Essay on Toleration and the Search after Truth” as well as “The Ant and Caterpillar, a Fable” and “Spring, a Poem.” One item resonated with news reported in the public prints and discussed in town squares: “An Ode on Liberty.”
Dunlap offered little commentary on the contents of the almanac, leaving it to prospective customers to assess the value on their own. Clearly, however, he believed that listing the contents would stimulate demand. Doing so provided a preview while also distinguishing this almanac from the many others printed, published, and sold in Philadelphia. If he had not considered listing the contents an effective means of marketing the almanac, he could have truncated the advertisement to just a few lines merely announcing its availability.
