Context
The Virginia Gazette office was Williamsburg's post office, and served as the colony's bookseller.
There were binders in VA and Williamsburg, but the pages of books were often printed abroad and imported
Between 1701-1780, an estimated 23% of books imported from England to North America and the Caribbean went to New England, 19% to Virginia and Maryland, 12% to NY, 9% to Pennsylvania, and 8.5% to the Carolinas.
By 1770, Virginia imported more than 40% of all English books shipped to North America
