"Introduction to the Second Edition"

This essay by Sonia Saldivar-Hull was added in the second edition of Borderlands.  It is helpful in explaining some things that might not be obvious to the reader, and it provides an overview of the book.  But it is rather academic--and if you want the most authentic experience of the book, you might want to start reading, then come back to the Introduction later.  To find out more about Saldivar-Hull, visit her faculty page at the University of Texas San Antonio.
