• While smartphones and tablets seem to be sending guidebooks the way of the dodo, some of us are still addicted to these little gems of information. Really, though -- do you need a whole stack of them? One good, comprehensive guidebook should do the trick. 
  
  Top Tips:
• If you are convinced that each of your 11 guidebooks offers unique and vital information about your destination, cart them to your office or the library and photocopy your favorite sections.
   
• Lonely Planet offers mix-and-match guidebook chapters that can be downloaded as PDF's from its Web site, while Frommer's offers electronic versions of its guidebooks for smartphones and tablets. Carrying one gadget with all the info will save you significant weight over multiple books.
