introduction the act of beginning something new; "they looked forward to the debut of their new product line"
textual matter,
text the words of something written; "there were more than a thousand words of text"; "they handed out the printed text of the mayor's speech"; "he wants to reconstruct the original text"
A foreword is a (usually short) piece of writing often found at the beginning of a book or other piece of literature, before the introduction; this may or may not be written by the primary author of the work. A preface, by contrast, is written by the author of the book, although sometimes the two terms are used interchangeably. A preface generally covers the story of how the book came into being, or how the idea for the book was developed; this is often followed by thanks and acknowledgments to people who were helpful to the author during the time of writing.
