The Manhattan Family Guide to Private Schools: Fourth Edition by Victoria Goldman, Catherine Hausman
While there are many college guidebooks available, unfortunately there are only a few books about NYC private schools. And despite the different titles, these books often contain content written by the schools themselves.
Refreshingly, Goldman and Hausman's book is different because it is written by two private school moms. Seeking input from private school parents and students, the two authors offer more inclusive profiles than are available elsewhere. As a local educational consultant, I often recommend this book to my families as a good starting point for their research. The new edition is more comprehensive than ever.

If You're Thinking of Living in ...All About 115 Great Neighborhoods in and Around New York by Michael J. Leahy (Editor), Mike Leahy (Editor)
This book is good for broad overviews of the various neighborhoods in and around New York City. Thus it might be particularly helpful for the reader who is not at all familiar with the Big Apple and its surrounding communities. Not a  good source for information on apartment rental markets. Info favors familes with children over the young, single  professional.
