These days, plenty of people are interested in travel. However, with rising gas costs and higher flight fares, more and more people are traveling vicariously through photo books.

For those photographers out there, this is great news on a lot of different levels. First, it gives them a chance to expose others to their favorite places - and the photos that they have taken over time.

More importantly, it gives professional photographers who understand the advantages of self-publishing to get their work out there now, to promote their books and to take advantage of a trend that's increasingly hot.

The best part about self-publishing travel books though isn't even just the demand. The best part is that you're able to get your work out there and show off the roads less traveled as well.
