Time Management book ? Hmm... there are tons of these books on the market. From what I have, to begin with, read First Things First by Stephen Covey. In my opinion, for effective time management, how you prioritize is quite important, so please check it out. Or, you could search the Net for free ebooks on time management. I am sure there are plenty around. Find a system that fits you

If you want to manage your time i reccomend a book for project management too. I liked Project 2003 Personal Trainer. It shows basics very quickly and in an efficient way. For advanced features i am reading other books now. I am a newbie for time management too and will check the suggestions here. Green reps sent to the owners of the suggestions.
Time Tactics of Very Successful People by Griessman is very good. There isn't any filler in it, and its practical. You might have to get it used.
Getting Things Done seems to be one that people recommend. I've read the book, and it's pretty good one.
