What Books Adequately Represent an LIS Degree?

Deane Barker writes “I am contemplating a Masters in LIS. I really want a Masters in Content Management (as discussed here), but an LIS degree seems to be the closest thing to it.

However, I’m wondering about my level of interest and/or passion for LIS. What I’d like is for the community to recommend two or three of the seminal books in the LIS field, so that I can read them and see if any of it “trips my trigger,” so to speak.

So, what books can the community recommend that pass the following test: ‘If you love this book, then an LIS degree is just what you’re looking for.’? Put another way, if you had to represent an LIS degree in a single book, which one would it be?”
