What is the passage mainly about? [originaltext] If you look closely at some

If you look closely at some of the early copies of the Declaration of Independence, beyond the signature of John Hancock and the other 55 men who signed it, (12)you will also find the name of one woman, Mary Katherine Goddard. It was she, a Baltimore printer, who published the first official copies of the Declaration. (13)Mary Goddard first got into printing at the age of twenty-four when her brother opened a printing shop in Providence, Rhode Island, in 1762. When he proceeded to get into trouble with his partners and creditors, it was Mary Goddard and her mother who were left to run the shop. In 1765 they began publishing the Providence Gazette, a weekly newspaper. Similar problems seemed to follow her brother as he opened businesses in Philadelphia and again in Baltimore. After starting Baltimore’s first newspaper, The Maryland Journal, in 1773, her brother went broke trying to organize a colonial postal service. Mary Katherine Goddard’s name appeared on the newspaper’s masthead for the first time. During the American Revolution, Mary Goddard continued to publish Baltimore’s only newspaper, which one historian claimed was "second to none among the colonies". She was also the city’s postmaster from 1775 to 1789—appointed by Benjamin Franklin—and is considered to be the first woman to hold a federal position.
