According to the Introduction, this book attempts to record over 1,400 of the publications, almost all with exceptions noted, of New London printers from May 1, 1709 through the year 1800. The output of the several presses was surprisingly large because all the printing done between the spring of 1709 and the autumn of 1754 in the Colony of Connecticut was done in New London. Johnson also includes twenty-three British Royal coats-of-arms used on New London printings of colony laws from 1709 to 1775. The appendices include sections on the Rogerenes, newspapers published in New London in the 18th century, election sermons printed in New London, and New London printers and booksellers.
