The Princetown Review publishes a number of college search-related books, including the "Complete Book of Colleges" and this one. This book is essentially a distilled version of the "Complete Book", and frankly a lot more useful (but for people completely new to the college-searching process, definitely check that out too).
"The Best 376 Colleges (2012 Edition)" (840 pages) is similar to last year's edition. After holding the number of best colleges at 373 last year (remember this book started off in 1992 with the best 250, where have the years gone!), this time there are 6 new "best" colleges: Champaign College, Christopher Newport University, Portland State University, Roanoke College, the University of Houston, and the National University of Ireland, Maynooth. Three schools from last year's list were dropped (but if the inflation of "best" colleges continues, I surmise we'll get to 400 by 2020 or so). There are over 60 fun-to-browse top 20 lists of best/worst, such as "Most Beautiful Campus", "Students Study the Most", "Party Schools", and "Most Politically Active Students" (my daughter is attending the #5 ranked school on that list, it was ranked #1 last year, so yes these rankings change from year to year, although not sure how exactly these rankings come about, a drop from 1 to 5 in a single year seems pretty steep).
The best feature of this guide remains the 2 page layout for each of the colleges, with in-depth information on campus life, academic selectivity (the number of applicants, how many were accepted, and of those how many actually decided to attend), up-to-date tuition and room/board costs (I checked the numbers of the college that my daughter is now attending, and they are accurate), etc. Another aspect that is very helpful is the "Survey says" sidebar, in which the essence of the university is distilled from the college students themselves, and "The Inside Word" segment on how tough it really is to gain admission when all is said and done. I can't help but notice that the tuition and room/board numbers for Xavier Univeristy, a fine Jesuit school here in Cincinnati, are completely wrong (they are double from what is listed in the book), an unlikely and uncharacteristic mistake.
In the end, the proof is in the pudding: of the many college guides out there, my daughter spent more time with this book (when she was looking at colleges a few years ago) than with any other. This book is not the first place to start the college search, but once your son or daughter has narrowed down his/her colleges of choice, and assuming those colleges are featured in the "best 376", this book clearly is the best resource, the last step before a campus visit, and can be used again following the campus visits. I've looked at a lot of college-search books and if I was forced to recommend only one book among all the college search guides, this book is it, period.
