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

“I beg the Favour of such Tavern Keepers to send their Names immediately to MILLS and HICKS.”
The first advertisement in the October 3, 1774, edition of the Massachusetts Gazette and Boston Post-Boy, purportedly placed by Isaac Bickerstaff, announced the impending publication of an “ALMANACK for 1775.” Bickerstaff, however, was a pseudonym. Benjamin West provided the astronomical calculations, though Nathaniel Mills and John Hicks, the printers of both the newspaper and the almanac, likely compiled the rest of the content for Bickerstaff’s Boston Almanack, for the Year of Our Redemption 1775. That explains the privileged place the advertisement received.
Yet Mills and Hicks did not insert this notice immediately after the news merely in hopes of increasing sales for the almanac once it went to press. They also deployed it as a means of crowdsourcing some of the contents. Writing as Bickerstaff, the printers requested, “If any new Houses of Entertainment have been opened, or if any were omitted in my last ALMANACK, I beg the Favour of such Tavern Keepers to send their Names immediately to MILLS and HICKS.” The printers would then pass along those entries to “Bickerstaff” to incorporate into “his” forthcoming almanac, but any proprietors who wished to have their establishments included needed to act quickly or risk missing out on the opportunity.
This advertisement previewed some of the useful contents of the almanac for prospective buyers, including those who lived outside Boston but might have occasion to visit. Yet Mills and Hicks did not provide a list of taverns only to direct readers to “Houses of Entertainment” where they could eat, drink, and socialize. Instead, they put together a guide to places where customers could expect to discuss politics and learn more about current events, realizing that taverns were popular places for stoking political engagement during the imperial crisis. At the time Mills and Hicks published their advertisement, the harbor was closed due to the Boston Port Act and the other Coercive Acts enraged residents of city. Mills and Hicks disseminated news and opinion via their weekly newspaper, but they also knew that a lot of information circulated among patrons gathered in taverns. A list of “Houses of Entertainment” served as a compendium of places for discussing politics and hearing the latest updates before they appeared in print.
