Legal Frontiers Book

I am using this book as the textbook in my class on information systems and analysis. All of the other books I found covering information economics were written at the graduate level or were research monographs. This book, in contrast, is quite accessible to an undergraduate. It covers modern, interesting material with clear exposition. My only complaints: there are quite a few typos; and sometimes the book is almost *too* elementary for students taking my class, and I have to supplement with more advanced material.
