The LSAT/LSDAS Registration and Information Book is a comprehensive and free guide to the law school application process.
Looking at Law School, edited by Stephen Gillers and published by Meridian, a division of Penguin Books, is one of a number of books about the law school experience.
Two books about what it's like to be a lawyer:
The Lure of the Law, by Richard W. Moll (published by Penguin for $9.95), is subtitled, "Why People Become Lawyers and What the Profession Does to Them." Moll is a former dean of admissions at several colleges.
Full Disclosure: Do You Really Want to Be a Lawyer?, was compiled by Susan J. Bell for the Young Lawyers Division of the American Bar Association and is published by Peterson's Guides for $11.95. This book is useful because it discusses many of the careers/jobs you could pursue with a law degree. It also explores the high points and low points of being a lawyer.
Books to help you select law schools:
The Official Guide to ABA-Approved U.S. Law Schools. It's well worth the price because there are grids for most of the schools which you can use to make a quick approximation of your odds of getting in. The text is boring and unrevealing, but the grids are extremely important tools. Highly recommended.
Top Law Schools (The Ultimate Guide), by Bruce and Kim Stuart, published by ARCO/Prentice Hall Press. Covers 56 schools. Vastly more informative than the Official Guide.
The Insider's Guide to the Top Fifteen Law Schools, by Cynthia L. Cooper, published by Doubleday. The introduction lists another 15 schools as well, so this is a reasonable place to see what other people consider to be the top 30 schools. Take such rankings with a grain of salt.
Public interest materials:
NAPIL (The National Association for Public Interest Law) offers a number of publications, including, for example:
