This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book considers the perspective of the world of print as a vantage point from which to observe the shifts in early modern Irish society. It explains the first attribute of print, its existence as commodity, to chart some of the revolutions that took place in the supply of books in the early modern period. The book deals with the second attribute of print by attempting to construct how contemporaries used the books they had bought, borrowed, stolen or heard others read aloud. It also deals with the significant shift in the social context that took place in early modern Ireland which enabled writing to become an accepted part of that world.
