Some travelers like to save guidebooks used on vacations as a reminder of places they have visited. Others give them to friends or family members traveling to the same place. Now, there is a third option.

The Web site      http://www.GuideGecko.com    which is a publishing platform and bookstore for travel guides, is offering free listings for travelers to sell their used travel guidebooks.

Travelers can list their guidebooks free of charge in a process that takes less than 20 minutes to complete. The seller decides on the price and sets the shipping costs. Titles are listed immediately. Once sold, GuideGecko collects the customer payment and sends an e-mail with the shipping details to the seller, who receive 85 percent of what the customer pays.

The bookstore on the Web site offers guidebooks for more than 70 categories and 169 countries.
