Hands down "Heading Home With Your Newborn: From Birth to Reality" for newborn care basics. "Baby 411" is also valuable.
"The Wonder Weeks" is great for knowing why your formerly happy baby is suddenly cranky, clingy, and fussy.
I didn't find any one sleep book all that helpful for my difficult sleeper. Ferber has a popular sleep training method but his book seems to actually be geared towards kids rather than young infants and his sleep totals are really low, though there's good info on how sleep works in their. Weissbluth's book is so poorly organized that it's only looking back on it that I realize how little of his information made sense. Kim West's book was fairly good - I might start there if you need a sleep book. No Cry Sleep Solution isn't bad, but the information didn't work for my kid.
In my opion there's a gaping hole in the market for a book that is like Babywise or The Baby Book by Sears but without either the really strict parent-directed or attachment parenting slants. I did not find a middle-of-the-road comprehensive guide to feeding, sleeping, playing, development, and so on. I would have loved a guide that gave me an idea of how all the aspects of baby care relate, but without a strong agenda and I couldn't.
