In his early days as a printer, Bradford published an almanac , "Kalendarium Pennsilvaniense" by Samuel Atkins. In the almanac, Bradford apologized for errors caused by his troublesome travel but hoped that readers would appreciate the hard work he underwent in order to bring print to the Middle Colonies. The publication received immediate attention, especially from Pennsylvania Governor William Penn who took offense at a reference to him. Atkins was quickly reprimanded for the incident and Bradford was told not to print anything unless it was approved by the Pennsylvania Council. Later in 1687, Bradford was informed not to print anything about Quakers unless they approved it beforehand. In 1689, the new Pennsylvania governor John Blackwell was outraged and officially reprimanded Bradford when he printed William Penn's original charter for the colony. Bradford argued that he printed what he received and was not liable. Bradford then quit his business and briefly went to England, to return in 1690. 
In Of Plymouth Plantation , Bradford saw what was happening to be like what happened in the Bible. As Philip Gould writes, "Bradford hoped to show the workings of God to future generations."  :349 The book was not published until 1656, the year before his death, and it was well liked. Bradford has been called the father of American history.  :151 Many American authors have put what Bradford said in their books. Thomas Prence did so in his book named A Chronological History of New-England in the Form of Annals. Today it is considered very important and studied in American schools and colleges. Bradford's journal was included in another work entitled Mourt's Relation . This was written in part by Edward Winslow , and made into a book in England in 1622.
