Guide books are a critical piece of the travel industry. Like most publications, many travel guides are being moved online, making more content available for readers to find on their phones and computers rather than book stores and libraries. However, in this niche of the publishing world, there is a difference between printed information and posted information. Online travel guides provide quick information about where to stay, what do to, and how to make the most of a limited budget or time window on a trip; guide books provide more in-depth knowledge about specific places. This gap between the two sources ensure that online and in-print travel guides will not compete with each other, but rather complement each other. This is a unique dynamic as most current publications are being replaced by their online companions. Guide books, instead, are expanding to occupy both digital and print publications, not just moving away from print toward digital ones.
