What do you want? What to do/expect kind of guide, or reassurance, or fact based information?
What to do - I have never found a very good all-rounder. I can recommend different books for different aspects of parenting! The other problem here is that there are several schools of thought about how babies work, and they all disagree with each other, so it might be worth picking one or alternatively reading about all of them and seeing which makes the most sense to you.
(The four I can think of offhand are Attachment parenting - for which you want something like the Sears Baby Book, RIE for which you want anything by Magda Gerber or Janet Lansbury, anything routine based - any routine/supernanny type book, or something like Harvey Karp where they promise foolproof settling techniques!)
For reassurance separate from parenting style, What Mothers Do is excellent.
For fact based information, you're better off finding trusted sources of information online and sticking to those as they will be updated far more regularly than books. Even a book published last year will often have been written 2-3 years before, so the most up to date information is often omitted.
NHS - for any basic questions/health related questions
Lullaby Trust - sleep safety
Kellymom - breastfeeding advice
I can't think of any more just now.
