Query: Great book

Ordered the book in order to use it as a resource for a paper in my writing class. Read the book very quickly and it was a very good book. For being a used library book, it was actually in very good condition, in some ways, it was hard to tell it was a used book. Altogether, very good purchase, and cheap for a college student writing a paper.
