I would not recommend going to a book without going to at least a good Intro course, because a good class with participants sharing their thoughts and experience and a empathic instructor is really worth having in contrast to reading a 300 page tome.
Post course, however, a reference book is worthwhile as it is another learning approach. Which book though? A search to Amazon shows these candidates:
- Viescas and Conrad, both long time authors have Access 2007 Inside Out
- Roger Jennings (he with the classic Access 2.0 tome) has Special Edition Using Microsoft Access 2007
- The famous Micheal Groh, Cary Prague, then Stockman and Powell have the Access 2007 Bible
